The Standing Dead

Not sure if anyone else has been experiencing this with the same consistency as me, but I've been getting a fun new bug ever since entering the underdark where characters that are initially alive but then get killed (either by me or another NPC) will "re-die" every time I re-enter the area they are in, complete with groaning and collapsing to the ground (which was mildly unnerving to watch Nere do after I cut his head off). It's now progressed to the characters being dead, but just staying standing and performing idle animations as I loot their corpses. It's pretty funny to be honest, but does break the immersion a bit!
