Everything was working fine until I began the world event to fight Goneril. She just stood there and let me kill her while shouting out her usual lines. After killing her I fast traveled to fight one of the zealots(Eorforwine) and he just stood there and didn't fight back. I would get his health low but then he would regenerate health so I couldn't kill him. I moved on from him to continue the main story quest in Cent. I started a raid at Rouecistre Blockade and all of the enemies are walking around like nothing is going in and letting me assassinate right in front of them. My raiding party isn't fighting them either. I'm playing on PC and have over 59 hours in it so far. This is the first time I've seen this happen.
