I left some loot from an enemy on the roof during House of Bones and I can’t fly up there because I can’t initiate combat again! It’s probably just a small thing but there should be a way to get it down! It’s still there on leaving and reentering the area!
Agee, for example my screenshots with flying box
Usually, standing underneath the loot bag will let you pick it up, but the positioning can be a bit finicky.
