The two `Spawner (225)` entries at 1333,1808 in `shared/felucca/Vendors.json` and `shared/trammel/Vendors.json` name `escortablewanderinghealer`, which no class has. `BaseSpawner` marks the entry `InvalidType`, so the spawner never spawns anything.
This changes the entry to `EscortableMage`, the only `Escortable` class. It already spawns in Britain in `TownsPeople.json`, and a vendor spawner at 1351,1816 nearby uses it too.
If the original intent was a different type, or the spawner should go, I can change that.
