We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
It's possible that you might hace a corrupted save file. If deleting your profile doesn't work, then try clearing your cache. That will delete all the updates on your console. If that doesn't work, then my only suggestion is to delete your save file.
