The most annyoing part of it is when your character is a thieving Druid like mine.
I have to start sneaking a long way offscreen from my target so to not accidently make him move. So thers also this Time consuming fact.
As my Druid is face of party, she does the talking and the Thieving part. Both require NPCs to stand still.
THEY DONT ;(
Ill hope this is only a problem with the "Tag's" on Characters internal descriptions in the Code, how NPCs are reacting to Player Character.
That it s only a fast and easy fix to check up why the problematic "Tag" persists after Shapechanging or even beeing Dead right in front of the NPCs eyes and revived.
I tested it and killed my Druid right before BREM in the Zhent Hideout.
After my PC die, Brem was doing normal again. Not fleeing before a illusionary Animal, whatever he sees

But reviving my Druid just spooked him again... ;(
Persistent Curse, i call that.
