So I am on chapter 8 in the inferno at the save point right by the rare Nevi. I tried several times to kill it and have failed. For some reason now whenever I hit R to fly away from the platform the camera starts spinning madly and I can't see where I'm going. I have no idea why this started happening and the game is now completely unplayable. I tried changing some viewing options but nothing seems to work. Has this happened to anyone else and is there a fix?
