So as of a few days ago I have been having this very strange bug and it has gotten progressively worse. While I walk, my character will repeatedly stop/shake/not quite move right as though he has run into a small invisible wall. My game is saved to my hard drive and has been since the release so it's not an error because of a scratched disc.

Has anyone else had this error and or know how to fix it? If my description was a little vague or weird I'm sorry, just ask for clarification.

Please help, thank you.
