+1. The same rationale for the mechanic where bots can’t take fall damage applies here. Since bots can’t path around or avoid the plague/acid pool, they should not take acid damage. It seems that they just slapped the Vermintide 1 bot pathfinding in there. In Vermintide 1, there is no damage from the acid pool in Garden of Morr.
The same thing applies to Chaos Wastes AoE curses: e.g., exploding totem (Khorne), Blood Tornado (Khorne), hexed poisoned enemies (Nurgle). Bots can’t path around or avoid these AoE curses, so they shouldn’t take damage from them.
