I just got Stubbs and played it for a while. When I exited the game my console froze. Turned off the console, then back on and could not sign in with my gamer tag, it froze at sign in. I had to call microsoft which directed me to delete the save file and recover my gamertag. Evidently there was a problem with my save file. Has anyone else has this issue? Anyone know how to avoid it in the future?
