Completion Reset

My completion status went from 48% to 3% last night, even though it shows all my achievements as unlocked still. My Halo gamerscore also went from 1500+ to 230, even on Halo waypoint, but if you look at my achieves you can tell that there is no way my GS is that low. Has this happened to anyone else?

I’ve quit and restart Halo, signed in and out of XBL, hard reset, waited over night. Nothing seems to help.

Nevermind it appears that it’s an issue with XBL not MCC. 48% of my unlocked achievements reverted back to the “Done… Unlocking!” status for some reason. And the 3% i got last night from Spartan Ops stayed unlocked.
