Halo 4 Ranks Glitched?

I haven’t played Halo 4 since May, have played quite a bit of it. When I loaded it up for the first time today my rank is back to 1 and all my items are locked again…the only thing that is still the way I left it was the color of my armor, service tag, and emblem are still the same.

Anyone else have this problem and/or know of a fix?

Did you mod it?
