All classes and points reset??

So I just started up Halo 4 after playing some campaign I turned of my console and when I went back my Multiplayer classes were all reset and all my spending points were reset to i believe 53… So i needed to buy everything unlocked again and needed to redo my classes…

Wtf?

This has happened to me twice (also after having played some Campaign). It’s very annoying and I don’t want to play Campaign until it’s fixed.

I think 343i are aware of the issue. It started since downloading the Champions Bundle.
