Sigh..... The old generation of Xbox 360 is rapidly losing my faith in it. Sorry. So, if any old gen Xbox users have a problem of the game locking up and a workaround or fix, could you tell me? I mean, this is a common problem for me, looking at you, GTA V, but this is just South Park. So help me.

How far along are you? If you're near the beginning, try a new character. Otherwise you could try an old save before you had the issue.

I'm having the exact same problem. When you say do you say to get new charcter do you mean butters or somebody else? because I can't change to any other character that early in the game.

No, start a new PC. My buddy Josh started a Jew character, the game applied a new patch and all of a sudden it wouldn't save properly for him after that. It also started deleting some of his old saves. He then made a new character and it ran perfectly fine for him after that.
