Gaga keeps giving you the quest that gives Mardi Gras Feather, even after you completed all 3 quests that require the feathers. Could you disable this quest after the player has completed the 3 quests that give you Mardi Gras Masks?

Found it. The server accepts at most 10 pickup requests per second, and a pet walking a spread-out pile sent one per frame, so together with holding Z it went over the limit and each refused request stalled for a second. Pickups are now batched (up to 8 drops per request). In a 200-drop test, 139 were picked up in 10 s, up from 98, with no stalls. Also fixed chubby's note: Gaga stops offering the Mardi Gras Feather quest once all three mask quests are done.
