## Summary
With T2A packet crafting menus enabled (`t2aCraftMenus`, default for pre-UOTD eras), cooking did nothing. Double-clicking a Skillet set a target, and `T2ACraftSystem.ShowMenu` had no Cooking branch, so the target was accepted and silently dropped. Nothing else could cook either: the old RunUO "use food on a heat source" code was never hooked up and was removed in #1054.
T2A cooking never used a menu, so this restores the item-on-item / item-on-heat-source flow:
- **Per-item handling:** each ingredient (`CookableFood`, `Dough`, `SweetDough`, `SackFlour`, `BowlFlour`, `JarHoney`) implements `IT2ACombinable.TryCombine` and switches on the target. `T2ACooking` holds the shared target, water, combine and heat-timer helpers.
- **Heat source:** all `CookableFood` (raw meats, fish, eggs, unbaked pies/quiche/pizzas, cookie and cake mix), dough → bread loaf, sweet dough → muffins. One unit is used up at the start, then a 5 s timer; the Cooking check runs from `CookingLevel` to 100 (bread and muffins use `DefCooking`'s range). The food burns on failure or if the cook moves more than 3 tiles away.
- **Combinations:**
- Open flour sack or bowl of flour + water → dough
- Dough + pear / peach / apple / pumpkin / eggs / meat / sausage → the matching unbaked pie, quiche or pizza
- Dough + honey → sweet dough
- Sweet dough + honey → cookie mix
- Flour + sweet dough → cake mix
- The honey and flour + sweet dough recipes work in either direction.
- **Water:** water drinks (pitchers), buckets, barrels, tubs and trough add-ons, in the pack, in hand, or on the ground within 2 tiles and in line of sight.
- **Cooking tools are passive:** with T2A menus on, a tool whose system has no T2A menu (`T2ACraftSystem.HasMenu`) falls through to `ShowCraftMenu`, which does nothing under T2A. No dead target is left.
Behaviour with T2A menus off is unchanged.
## Follow-ups
- Static troughs/barrels and open water aren't water sources here or for pitcher filling (no static water ID list exists); to be fixed separately.
- Whether a bowl of flour returns an empty bowl is unconfirmed (`//TODO`).
- Cooking tools that must merely be in the pack for some recipes are not modelled yet.
## Testing
- `dotnet build`: 0 warnings, 0 errors
- New `T2ACookingTests`: flour + water, closed sack refused, dough + apple, honey in both directions, cookie mix, cake mix, wrong target consumes nothing, water in another player's pack refused
- Not covered: the heat timer (untested); not yet exercised in game
## Summary
The T2A crafting menus offered items the chosen resource couldn't make:
- **Tailoring honours the targeted cloth hue.** The menu was built from all cloth in the pack, but the craft consumes only the targeted hue, so it offered items that then failed on resources. `CanCraftItem` / `FilterEntries` / `AnyCraftableInCategory` now take the hue and count with the same helper the craft uses.
- **Uncut cloth counts in the hued path.** The hue-aware count and consume matched only `Cloth`, so targeting uncut cloth gave an empty menu. The hued path now uses `CraftItem`'s equivalence table like the unhued path. `T2ACraftSystem` reuses that table instead of a narrower copy, which also covers the coloured woods and leathers on later-era shards.
- **T2A tinkering only uses iron ingots.** Coloured ingots are refused with a re-prompt. The menu filter now uses the selected ingot, and Make Last for tinkering always resolves to iron, so a coloured choice left over from the gump flow can't be used.
## Testing
- `dotnet build`: 0 warnings, 0 errors
- New `T2AHuedFilterTests`: only cloth of the targeted hue counts, and uncut cloth of the same hue counts toward the recipe
- No test for the tinkering target and message flow; not yet exercised in game
## Summary
About 114 tests skipped on CI because they needed the official client files (`tiledata.mul`, map and multi files). They gave CI no signal, and locally they ran against whichever client a developer had installed. The test hosts now build their own world instead, so every test runs on CI and runs the same on every machine. CI simulation: Server.Tests 837 passed, UOContent.Tests 1131 passed, **0 skipped**.
- **Generated tile data.** The fixtures write a pre-HS `tiledata.mul` from a small invented tile kit (`Server.Tests/Terrain/TestTiles`) and load it through the real `TileData.Load()`. The test hosts no longer read any client directory (`MODERNUO_CLIENT_PATH`, `MODERNUO_TEST_DATA_DIR` and `C:\Ultima Online Classic` are gone from test code). The file is written to `SyntheticData` in each test project's output, overwritten every run and removed by `dotnet clean`.
- **Injected terrain.** `TestTerrain` stamps land and statics into Felucca and Trammel, which share one terrain. Writes after startup must go in a `TestTerrain.Scope()`, which puts back every block it touched and keeps the step cache fresh.
- **Prefab scenes.** Seven named scenes (town, causeway, sewer walkway, coastline, deep sea, map-edge sea, an upstairs room with an L-shaped counter) replace the Britain coordinates the pathing, AI and fishing tests relied on. Each scene-based test asserts its scene is present first, so a missing scene fails instead of passing on flat ground. Stamping all seven takes 3-5 ms.
- **Multi footprints.** Contrived footprints for the three multi IDs content looks up (0x74, 0x7A, 0x0) are seeded through a new internal `MultiData.SetComponents`.
- **Fingerprint.** `StepCacheFile.HashTileDataFile` is extracted so a test can show that a one-flag change to the file changes the fingerprint, while runtime table mutation does not.
### Engine changes
- `TileMatrix.GetLandBlock`/`GetStaticBlock`: on a map without its files, return the block injected with `SetLandBlock`/`SetStaticBlock`, or the default when nothing was injected. Maps with files take the same path as before.
- `MultiData.SetComponents` (internal): registers a footprint without multi files.
### Test changes worth a look
- Values that were properties of real Britain terrain (probes at Z 10, a pinned plain walk mask of 0xC1) are re-pinned to the synthetic plain (Z 0, 0xFF).
- No tests were deleted. The multi walkability and boat-deck tests assert movement behaviour over a footprint, not what a real multi looks like, so they run on the contrived footprints.
- Maps 0 and 1 keep file indexes 0 and 1, and every stamp writes both, rather than sharing one file index. On a map without files the getters never consult the shared-file cache, and its patch bits would hide one facet's injection from the other.
## Test plan
- [x] `dotnet test -p:SolutionDir=... --filter "Category!=Manual"` with the client env vars pointed at an empty directory: 837 + 1131 passed, 0 skipped, 0 failed
- [x] Mutation check: removing the step-cache clear from `TestTerrain` makes the stale-cache tests fail
- [x] CI green on all platforms
Stacked on #2716. Retarget to `main` after it merges.
## Problem
Mobiles a champion summons mid-fight aren't tracked by anything:
| Summoner | Minions |
|---|---|
| LordOaks | Silvani queen |
| `SummonPixiesCounter` (LordOaks, Silvani, Twaulo) | 3-6 pixies per trigger |
| Barracoon | 3-6 ratmen per trigger |
`ChampionSpawn.DeleteCreatures` (called on expiry and when the spawn is deleted) clears only `Creatures` and the champion. These minions survive every reset and stay in the save. I surveyed every content creature that creates other mobiles; the others already clean up after themselves: Meraktus deletes its followers, Harrower kills its tentacles, PlagueSpawn and the Enraged animals delete themselves when their owner is gone, and BogThing eats its boglings.
## Changes
- **`BaseCreature.SpawnMinion(minion, target, location)`:** sets the team, places the minion and sets its combatant. Ownership: if the summoner is a champion spawn's champion, one of its creatures, or one of its minions (found through the spawn region), the minion joins that spawn. It refuses, and deletes the minion, if the summoner isn't on a real map. `SummonPixiesCounter` read `source.Map` even though `MonsterAbility.Trigger` notes it can fire after the creature has left the world.
- **`ChampionSpawn.Minions`:** a new serialized list (v12, `MigrateFrom(V11Content)`) kept apart from `Creatures`:
- killing a minion never counts toward a level, so a leftover summoner can't feed a restarted spawn;
- `DeleteCreatures` deletes minions along with the creatures, which matches when the spawn is deactivated (`ExpireCreatures`, 10 minutes after `Stop`) or deleted.
- **Callers:** LordOaks, `SummonPixiesCounter` and Barracoon spawn through `SpawnMinion`. A summoner that isn't part of a spawn (a GM `[add]`) still makes standalone minions, as today.
## Testing
- `ChampionMinionTests`:
- the champion's queen is listed in `Minions` and deleted by `DeleteCreatures`;
- a minion's minion also belongs to the spawn;
- a Lord Oaks in the region that isn't the spawn's champion keeps a standalone queen.
- UOContent.Tests: 1237 passed, 2 skipped. The Application build is clean.
Part of #2687, after #2709. One commit per section, in the same order.
### Failures, maps, bottles and colored nets
A GM's cast fails about a quarter of the time in any water, from the fishing table's last row, and deep water is no harder than a river. Maps and bottles are 0.5% per roll from T2A on, and 1 net in 100 is colored in every era.
This removes the last row, so a cast only fails its skill check. From UO:R a cast in deep water checks skill from 65 to 115, through a `Fishing.MutateResource` override. Publish 5, which "was known as the Renaissance Publish", made deep water harder: "because the difficulty level is higher, the rate of success for pulling up SoS bottles will be lower." [O3] From LBR maps and bottles come up more often and 1 net in 10 is colored, both from Publish 16, which came out in parts during LBR [O14].
| Change | Era | Source |
|---|---|---|
| No "nothing" row | All | #2687 found no source for it; "A prepatch, you never failed catching something at GM" [S15]; a GM succeeds every time in lakes and rivers [C1] |
| Deep water: nothing below 65 skill | UO:R on | "The minimum required skill level to catch *anything* in deep water is 65." [S5–S7] |
| Deep water: 10% at 70, 70% at GM | UO:R on | "Even at 70, it is only about a 10% chance of success in deep water." [S14]; 29% of casts fail before Publish 16 and 30% after [F1, F2]; 70% success at 100 offshore [C1] |
| Maps (skill − 80) / 2400, bottles (skill − 80) / 1500 | LBR on | A bottle "about once per hour" until October 2002 [S1–S6], then "a special item (a net, a message in a bottle or a treasure map) about five times per hour" [S7]; bottles went from 0.4% of catches before Publish 16 [F1] to 1.7% after [F2] |
| Colored nets: none, then 10% | LBR on | "With Publish 16, we got a nice surprise--colored special fish nets!" [F4]; "Any net created has a 10% chance of being colored." [F3] |
- From LBR a GM's deep-water catches are 0.8% maps and 1.3% bottles. Chrome counted 0.9% and 1.3% [C1], the FCB 0.7% and 1.7% after Publish 16 [F2]. Nets and big fish stay at 0.5%, close to both counts.
- At Stratics' 280 casts an hour [S1–S6], that is about one bottle an hour from UO:R to UOTD and five nets, maps or bottles an hour from LBR, the two rates Stratics gives.
- The gain chance rises as the success chance falls, so above 65 a cast in deep water gains faster than one near land, Publish 5's "best method for gaining at high levels" [O3]. Below 65 it neither catches nor gains.
- Chrome's table also has three kinds of water near land, with difficulties of 15, 35 and 55. No other source has them, so near land stays at 0–100.
### Deep water is at least 14 tiles from land
`SpecialFishingNet.FullValidation` decides what counts as deep water: where a special fishing net works, where maps, bottles, nets and big fish can be caught, and from UO:R where a cast is harder. It checks the target and 20 points on its four diagonals, 5 to 25 tiles out. Nothing off those points is read, so a spot 8 tiles from shore can count as deep, while one with land 15 to 25 tiles away on a diagonal does not.
The sources give one rule in every era: land at least 14 tiles away. This checks every land tile within 13 of the target. ModernUO has no server lines inside a map, so the only boundary is the map's edge, which counts as land as before. Only land tiles are read, so statics such as rocks are ignored. `SOS.FindLocation` had its own copy of the old check and now calls `FullValidation`, so wrecks follow the same rule.
- 1999 to 2000: "which means you must be at least 14 tiles away from all land" [S1–S4]
- March 2001: "14 tiles away from any land mass" [F5]
- 2001 to 2002: "which means you must be at least 14 tiles away from all land and server lines" [S5–S7]
- Today: "You need to be a minimum of 14 tiles from land or a server boundary to be in ‘deep water’." [O9]
One guide from January 2000 says "16 tiles away from land" [S9]; every other source says 14.
- In the area an SOS picks from on Felucca, 59% of spots pass the old check and 63% pass the new one; in Ilshenar's two sea regions, 16% and 30%.
- The check reads up to 729 land tiles instead of 21: about 6 µs per check in a Release build, against under 0.1 µs before; a cast makes at most two.
### Sea serpents
In ModernUO a sea serpent comes up from fishing only with a treasure map, a bottle or a net, which it carries. A quarter are deep sea serpents. It has no timer, and nothing makes it attack the fisherman first.
This follows the notes of March 28, 1999 and Publish 4. A fished serpent attacks the fisherman at once. Five minutes after it surfaced it goes back to deep water, taking what it carries, unless someone is still fighting it: it took damage in the last two minutes and has not healed to full since, which is what ModernUO's damage entries record. From T2A, at 80 skill or more in deep water, 1% of casts also bring up a serpent that carries nothing, whether the cast catches something or not. 1 serpent in 10 is a deep sea serpent.
| Change | Era | Source |
|---|---|---|
| Attacks the fisherman at once | All | "Sea Serpents will now immediately attack the fisherman that brought them from the deep." [O1] |
| Goes back after 5 minutes unless fought | All | "Sea Serpents will return to deep water after 5 minutes if not attacked." [O1]; "will return to the depths after a brief period if they are not engaged" [S10] |
| 1% of casts bring up an empty serpent | T2A on | "Fishermen at over 80 skill will have a chance to pull up a sea serpent regardless of whether they succeed or fail at fishing when in deep sea." [O2]; 1% at 80 or more, before the skill check [B1] |
| 1 in 10 is a deep sea serpent | All | "A small percentage of Sea Serpents will be Deep-Sea Serpents." [O1]; about 10% [B1]; 9.8% and 10.8% of the serpents counted [F1, F2] |
- Publish 4 gives no rate. The 1% comes from a post by Hance, a UO developer, in December 2000 [B1]; T2A uses it too, since it is the rule Publish 4 brought in (our inference). The FCB's counts agree: 1.76% of casts brought up a serpent and 55% of serpents carried nothing, so about 1% of casts brought up an empty one [F1] (our calculation).
- Before Publish 4 serpents came up "on failure" [O1], and Stratics kept "if you are fishing with 80+ skill and you fail" from July 1999 to 2002 [S1–S7]. Publish 4 is the last rule in T2A, so it is the one used from T2A.
- Hance also relays a side comment that the empty serpent cancels the rest of the cast [B1]. If it did, no cast could bring up two serpents, but the FCB saw two from one cast on 0.96% of serpents [F1], and Chrome caught empty serpents together with fish and footwear [C1]. So the cast goes on.
- Hance's post also needs room in the backpack for a fish and fish left in the spot [B1]. A spot with no fish left already ends the cast before the roll, unless an SOS keeps the cast going (next section). A full backpack doesn't: ModernUO doesn't check for room before a cast, so neither does the serpent.
- Serpents from a special fishing net are unchanged; Hance's post says nets don't follow its formula [B1].
### The SOS chest
In ModernUO, a fisherman carrying an SOS within 60 tiles of its spot brings up the chest on 1 catch in 8 and a shipwrecked item on the other 7. The SOS also lets a cast go on where the fish have run out.
This makes the chest 1 catch in 4, in every era. From UO:R an SOS needs 65 skill, and below that the cast is an ordinary one.
| Change | Era | Source |
|---|---|---|
| The chest on 1 catch in 4 | All | "You have a 25% chance of getting the chest and a 75% chance of getting something else with each cast." [F3]; "a 25% chance to fish up the actual treasure chest" [S7] |
| An SOS needs 65 skill | UO:R on | 65 in the chest's row of Stratics' table: "The skills mentioned above are minimum skills needed to fish up the corresponding item." [S5–S7] |
- No source gives a number before October 2002, or any for ModernUO's 1 in 8, so the 25% applies in every era. The other catches keep ModernUO's seven kinds of shipwrecked items, equally likely. Hanse's die splits them in three: "One roll is body parts; another roll is shells, barrel staves, globes, etc.; another roll is paintings, broken clocks, etc.; and another is the chest itself." [F3]
- Stratics' guide of November 2000 has neither the chest's row nor the 65 for deep water [S4]. The May 2001 version, during Third Dawn, has both: "The minimum required skill level to catch *anything* in deep water is 65." [S5] The first section applies that from UO:R, after Publish 5 made deep water harder [O3], so the chest follows it (our inference). An SOS's spot is picked in deep water, but a cast within 60 tiles of it can be nearer land, so the 65 is checked on its own.
- Below 65 there are no shipwrecked items either, because Hanse's die is rolled once you "can even attempt to get a treasure chest" [F3] (our reading). Before UO:R an SOS still works at any skill; the only period line on it is "You do not have to be GM Fisherman to actually fish up the treasure from a bottle, only to fish up A bottle." [S9]
### Fishing reveals from T2A
ModernUO reveals a hidden fisherman from ML. The notes of March 28, 1999 already say "If you are hidden, fishing will now unhide you." [O1], so this reveals from T2A, at the same two points: the splash and the end of the cast.
### Big fish and the leviathan's artifact
In ModernUO every big fish weighs 3 to 200 stones and gives max(16, weight) / 4 steaks, and the net thrower has a 1 in 4 chance at an artifact at any skill.
| Change | Era | Source |
|---|---|---|
| Big fish weigh 100 stones | Before SE | "They weigh 100 stones each" [S5–S7]; Publish 28 "Added variable weight and fisherman's mark on big fish" [O6] |
| A steak per 5 stones, at least 4 | SE on | "now its weight / 5 will determine number of fish steaks (minimum of 4)" [O7] |
| The net thrower's own chance at an artifact: 1 in 4, only at GM | SE on | "Give the fabled net thrower (if a GM Fisherman) a 1 in 4 chance of getting a minor artifact (not modified by luck or damage)." [O6] |
- Before SE a big fish keeps ModernUO's weight / 4 steaks, 25 for 100 stones: no source gives a number before Publish 29.
- Publish 27 names only the attackers' chance: "Minor Artifacts will have a chance of spawning in each attacker's backpack after a paragon creature or a leviathan is slain." [O5] Publish 28 adds the thrower's roll [O6], so before SE there is none (our inference). The attackers' chance is unchanged.
### Magic fish
From SE the prized, wondrous and truly rare fish give +1 for 12 seconds instead of +5 for a minute [C1]. A Stratics FAQ of January 5, 2005 already says "The stat boost fish used to provide the person who ate it a +5 boost, but now it's only one or two points, and lasts only a short while." [S16]
- Stratics still gives +5 in December 2002 [S7] and no note dates the change. [S16], during SE, is the earliest source with the new values, so the eras before SE keep +5 and ModernUO's minute (our inference).
- Today's guide gives "Adds 8 – 12% to your Dexterity for 150 seconds when eaten" [O9]. No note dates that change either, so it is left out.
### The white pearl at an SOS's spot
From ML the white pearl is a bonus on top of the catch, but it went through `Fishing.Construct`'s SOS branch: at an SOS's spot the fisherman read "You have found a white pearl!" and got a shipwrecked item or the chest, a second SOS roll in the same cast. The pearl now skips that branch.

Part of #2687. Magic fish and footwear roll the same in every era: magic fish get rarer with skill (5% at 0 skill, 1% at GM) and footwear has a 20% chance at 0 skill. The leviathan rolls the generic 1% for its level 5 map.
A fishing table row can now end at an expansion, so each era gets its own magic fish and footwear rows. The chances at GM come from the Fishing Council of Britannia's cast counts before and after Publish 16, which came out in parts from April to December 2002, during LBR [O14]. The leviathan gets its 25% through a `BaseCreature.TreasureMapChance` override; leviathans only come from the fabled net, which already needs AOS.
| Change | Era | Source |
|---|---|---|
| Footwear: 75% at 0 skill, 2.5% at GM | T2A to UOTD | "The beginning fisherman will find this item on his hook most of the times" [S1–S7]; 2.5% of catches [F1] |
| Footwear: 75% at 0 skill, 10% at GM | LBR on | The same quote; 10.5% of catches [F2] |
| Magic fish: 80 skill, 2.5% at GM | T2A to UOTD | 80 from July 1999 to October 2002 [S1–S6, S9]; 2.4% of catches [F1] |
| Magic fish: no minimum, 5% at GM | LBR to SA | 0 from December 2002 [S7], so the minimum went in late 2002, during LBR; 5.6% of catches [F2] |
| Magic fish: 80 skill again | HS on | Still 0 in June 2010, during SA [S13]; 80 today [O9]. HS is the first expansion after that |
| Leviathan's map: 25% | AOS | Publish 27: "It also has a 25% chance to carry a level 5 treasure map." [O5] |
- These are chances per roll. The FCB's counts leave out empty casts, so they line up once the "nothing" row #2687 lists is gone (a follow-up PR removes it); while it stays, footwear is 3.2% of a GM's catches before LBR and 12% from LBR.
- No source counts footwear below GM, so 75% at 0 skill only follows Stratics' "most of the times". The numbers in my comment were placeholders.
- 80 again from HS is the one change beyond my comment, which proposed no minimum from LBR on.

## Summary
T2A tailoring Make Last failed after crafting a cloth item and then a leather item. `CraftContext.LastHue` was set only on the hued (cloth) path, so the next Make Last of a leather item took the hue-aware path and failed with "You don't have the resources". The leather path now resets `LastHue` to -1.
## Testing

- No automated test: driving `TailoringMenu` needs a NetState plus tiledata-backed resources, and CI has no tiledata. Not yet exercised in game.
The fishing mutate table offers every special catch in every era, so a pre-T2A shard fishes up boots, magic fish, treasure maps and bottles (added in the March 1999 fishing update), and a T2A shard gets the special fishing net and big fish, which no T2A publish or guide lists.
Each entry now carries the expansion that added it; the chances are unchanged. The nets in SOS chests and on krakens need UO:R as well, and before SE ancient SOS roll 1 in 40 and their chests aren't hued white, since Publish 28 changed both.
Two fixes from the same notes come with it. An SOS now only works in the facet it was found in, so kraken and leviathan bottles are made at death with the creature's facet. Big fish, their trophy deed and their trophy show the fisherman's mark and weight only from SE.
## Why each change
### The rule
- `Core.T2A`, `Core.UOR`, `Core.SE`… mean "the shard is this expansion **or newer**".
- An expansion includes every publish that came out while it was the newest one. Publish 27 (September 2004) came out before Samurai Empire (November 2004), so it belongs to AOS.
- An item can't drop on a shard older than the expansion that added it.
- When the sources only narrow it down to a window that spans two expansions, the item takes the older one, so no shard loses something it may really have had.
### When each fishing item arrived
| Expansion | Released | What it added to fishing | Sources |
|---|---|---|---|
| T2A | Oct 1, 1998 | Boots, magic fish, treasure maps, bottles (update of March 17, 1999) | [1] |
| UO:R | May 4, 2000 | Special fishing net (first listed in August 2000) | [2], [6], [7] |
| UO:R or Third Dawn | | Big fish (first listed between November 2000 and March 2001) | [3], [8], [9] |
| AOS | Feb 11, 2003 | Ancient SOS at 1 in 40, fabled fishing net (Publish 27, September 14, 2004) | [4] |
| SE | Nov 2, 2004 | Ancient SOS at 1 in 25, white ancient chests, the fisherman's mark on big fish (Publish 28, January 12, 2005) | [5] |
Release dates: [13].
### `Fishing.cs`
**`MutateEntry` gets an `Expansion` field and constructor argument.**
Each row has to know which expansion added it. `MutateEntry` is private to `Fishing`, so no other code is affected.
**`MutateType` skips rows newer than the shard:**
```csharp
if (Core.Expansion < entry.m_Expansion)
{
continue;
}
```
A skipped row behaves as if it weren't in the table. Every other row rolls exactly as before.
**The rows:**
| Row | Expansion | Why |
|---|---|---|
| Boots, shoes, sandals, thigh boots | T2A | The March 17, 1999 update is the first time fishing gives anything but fish: "you now have a chance of pulling up … One of any of several types of boots". [1] |
| Magic fish (prized, wondrous, truly rare, peculiar) | T2A | Same update: "Magical fish, which can boost stamina, strength, intelligence, or dexterity". [1] |
| Treasure map | T2A | Same update: "Treasure maps". [1] |
| Message in a bottle | T2A | Same update: "Messages in bottles". [1] |
| Special fishing net | UO:R | Missing from the 1999 list [1] and from the March 2000 fishing changes, which only mention treasure maps and SOS bottles [2]. Stratics' fishing guide doesn't have it from July 1999 to July 8, 2000 [6] and has it on August 10, 2000 [7], after UO:R came out. |
| Big fish | UO:R | Stratics' fishing guide doesn't have it from July 1999 [6] to November 7, 2000 [8] and has it on May 24, 2001 [9]. Publish 11 (March 14, 2001) already lets taxidermy kits use it [3]. So it is certainly not T2A. It came at the end of UO:R or with Third Dawn (March 7, 2001); the sources can't tell which, so it takes UO:R, the older one. |
| Nothing (the empty row) | None | Exists in every expansion; unchanged. |
**SOS chest, white hue: `if (sos.IsAncient && Core.SE)`**
Publish 28: "Hued level 4 fishing chests white." [5] It came out after SE, so before SE the ancient chest keeps its normal colour.
**SOS chest, net: `if (Core.UOR) { chest.DropItem(...); }`**
You can fish up an SOS chest from T2A on, because bottles are T2A [1]. The net inside it is UO:R (see the table), so before UO:R the chest comes without a net. The fabled net only goes in ancient chests, and those already need AOS [4].
**SOS: `from.Map == sos.TargetMap`, in `CheckResources` and `Construct`**
Both accepted an SOS whenever the fisher was in Felucca or Trammel, without comparing the SOS's `TargetMap`, so a Trammel SOS paid out in Felucca at the same spot. Publish 5: "SOS bottles and treasure maps will only work in the land they are found in (for instance, a map found in Felucca will only work in Felucca)." [14] Treasure maps already check their facet.
### `MessageInABottle.cs`
**`GetRandomLevel`: `Utility.Random(Core.SE ? 25 : 40) < 1`**
Publish 27 added ancient SOS at "a 1 in 40 chance" [4]. Publish 28 "Changed Ancient SoS spawn chance from 1 in 40 to 1 in 25" [5]. So AOS rolls 1 in 40, SE and newer 1 in 25. The `Core.AOS` check was already there.
### `Kraken.cs`
**Bottle, now made in `OnBeforeDeath`: `if (Core.T2A && Utility.RandomDouble() < .05)`**
Bottles don't exist before T2A [1], so a kraken can't carry one there. The 5% is unchanged; no official source gives a number. The kraken is in Stratics' 1999 creature list [10]; its kraken page says "Loot: Unknown" in January 2000 [11] and "Loot: Messages in a Bottle, Treasure Maps, 300 - 600 gold" in October 2000 [12].
The constructor packed the bottle before the kraken had a map, so it always pointed to Trammel; with the SOS check above, a kraken killed in Felucca would drop an SOS that only works in Trammel. It is now made at death with the kraken's facet, as `BaseCreature.OnBeforeDeath` does for treasure maps; the net already does the same for the kraken it brings up.
**Net: `if (Core.UOR) { PackItem(new SpecialFishingNet()); // Confirm? }`**
Nets are UO:R [6], [7]. The `// Confirm?` stays: in 2000 Stratics says the net was "loot on Sea Serpents" [7], [12], not on krakens. Which creature drops the net is out of scope; this PR only fixes the expansion.
### `Leviathan.cs`
**Bottle, now made in `OnBeforeDeath`**
Same as the kraken: it was packed in the constructor and pointed to Trammel. It is now made at death with the leviathan's facet, and still drops every time.
### `BigFish.cs` and `TaxidermyKit.cs`
**Mark and weight: `if (Core.SE && Weight >= 20)`, and the same in the trophy and its deed**
Publish 28: "Added variable weight and fisherman's mark on big fish, big fish trophy deed, and big fish trophy. Any big fish caught that is below 20 stones will not display weight or fisherman's mark." [5] It came out after SE, so before SE none of the three shows them.
### What this PR doesn't change
No chance, skill threshold or row order changes. The open questions (which creature drops the net, the exact expansion of big fish, its weight before Publish 28, the rates) are in #2687.

* fix: duel teams start on their own arena points, in formation
MoveInside clamped the team index with Math.Min instead of Math.Max, so
every team started on the west edge point. The formation rotation also
reused the already-rotated X when computing Y, stacking players on the
north and south edges, and the SW/NE corners swapped axes, which leaves
the corner formation pointing out of the arena.
* refactor: one start point index clamp for GetBaseStartPoint and MoveInside
The clamp was written twice, and only one copy was correct.
* refactor: leave the placement loop as it was
Only the rotation lines in the loop belong to the fix.
