May and I ran Vaults 6-10 and tested the team loot bug a few ways.... Solo mobs to each hunter least dmg looting = No Bug Solo mobs to each hunter/most dmg looting = No Bug Shared dmg on Boss mobs only/least dmg looting = No Bug Shared dmg on Boss mobs only/most dmg looting = No Bug Shared dmg on same mob/least dmg looting = No Bug I'm fairly sure those are the options we tried and couldnt reproduce the bug if that helps anyone.
