ever since launch, when i’m holding a bundle, out of nowhere, that bundle would just disappear/dropped. for example, in CoF path 1, after i got the flame and got past the boulders. as i wait for others to arrive the flame would just disappear like i drop it. pretty much every bundle that i can’t pick back up would be drop out of nowhere (i don’t recall ever picking back up any dropped bundle).
in a gathering material event/heart, i have had my quest item dropped on my way to the event npc, merely a couple of seconds after i picked it up. and sometimes it gets drop when i’m just standing still doing nothing. so i don’t think it’s anything i did that triggers it.
