I could report so many bugs but I don't do it because I do I don't want one-sided discussions.
found so many mistakes today alone ...
I know one that has been since day 1: If you try to steal consecutively the blacksmith at camp while invisible sometimes it turns whole camp into aggro even though you are obviously invisible and didn't get caught. So the script breaks somehow and they never go back to green. Obviously messes up your game. Resting doesn't return them to green either.
One way to avoid it: Run to the Zevlor area every time you finish stealing a bunch of things so the script doesn't detect you on the map. Go back once you make sure the smith resets his script.
Quickloading also messes up a lot of stuff in this game.
Just as a rule of thumb is better to just have a completely separate save before you start stealing and after you complete 1 npc and make sure something didn't break.
