Haven't really had issues with NPCs other than jahan's whiny ass keeps making me reload the game because every time he gets touched in battle he throws a tantrum and disappears....pussy.
Oh and I had a rabbit attack me once....no kidding, I didn't do anything to it, didn't try to attack it or anything. I entered an area and I saw the word "Fight" appear on screen and I was in combat mode. I was a bit puzzled because I couldn't see anyone at first, then I saw a goblin but he wasn't it, he was friendly and minding his business and that's when I noticed at the top of the screen a fluffy bunny rabbit in a red lined box....my sole nemesis!! I killed the bunny and combat was over and I traded with the friendly goblin afterwards. No idea what that was about. Maybe a bug but I'm not sure really....if I missed something and someone can enlighten me as to what the hell happened please do.
But beyond that ferocious bunny there was always a very distinct reason for why people attacked....like stealing, failed persuasions, me attacking someone and so on.
