I just started playing Shivering Isle and after I finnished the first ruin I noticed that the game was hacking. I whent to Third Person and noticed that when I run the character stops all the time and thats why it was hacking. When I let go of the controller I noticed why. The character where walking backwards by it self att some places. Not all the way, just every 2 meters or so. And when I tried an eralyer save I noticed that it was the same in all my saves? The character just starts walking backwards like he is drawn to a certin place and then he stops.
I tried clearing the cache, I even deleted the DLC and reinstalled it but it did not work.

The game hacking like this makes it almoust unplayable. Can anybody help me? Is this the bug they call A-Bomb? I have played over 400 hours before starting Shivering Isles.
