I have been having problems with the Nahant area. All the physics seem to go haywire. All objects(including my companion) are thrown around and teleported all over the place. It started after I completed Nahant Wharf and seems to only occur around the Nahant area, including the bridge entering the area, the wharf area, and the area around Croup Manor. It makes the area unplayable and worries me about it occuring elsewhere. I tried deleting and then re-installing the game, but that did not work.
I do have a link to a video I made of it occuring, but I cannot post links here. However, I really hope someone can help with this.
