Veerberg Act I
The fight prior to the boss fight - barrel was not collectable. Nothing we did (party wipe, host running away, party running away, host DCing) would allow the barrel to be collected, meaning everybody lost their loot (in this case, including 3 legendaries), as you cannot progress the game without that barrel being collected. Suggest auto-looting instead, as it was really disheartening to encounter. Happened on Legendary (6). Xbox Current Gen.
I have the same issues on my Xbox one
I'm on companions of icewind Dale halls of the duergar act 2 I get to the part with acid and beat the acid trolls and then the barrel spawns but can't collect
