XP disappearing

I play War Games matchmaking for awhile and then turn my XBox off or go to the Dashboard. When I play Halo again, the previously earned XP and even SR levels are no longer there and I’m back where I started off before. Anybody know why this would happen?

Maybe try going all the way to the Halo 4 menus before you go to the dashboard or turn the console off, to ensure that it saves the ranks.

I dunno, its just a suggestion.
Hope your problem gets fixed.
