A corpse's worn-gear list was fixed at creation, and clients learn worn gear only from the 0x89 packet sent on first sight. A piece lifted and dropped back showed as loose loot to everyone watching, but came back "worn" after a relog. Lifting now takes the piece off the list, so every view agrees it is loot.
Programmatic moves (the duel gather-and-re-equip in `DuelContext`) don't go through `OnItemLifted` and still see the original list.
