When Hans gets to the camp he gets off his horse and starts walking back to Rattay until he gets to his room and stops, I don't have the option to talk and nothing seems to fix it, I've reloaded saves and tried knocking him off his horse and attacking him. Does anyone have a fix? I've read other topics on this bug but their was no fix.

I do not own any of the DLC

have you tried verify/repair?
