The Stats system.. What happend?

I really never cared about this until now, but The title update once again has erased some memory from my disc, All the campaign missions I completed are gone and I will have to do the whole campaign again without being able to go to the level I want. And Waypoint seems to have not once updated anything about my progress I even have the same recruit armor. I get your busy and I appreciate the New free Forge map, but This has been going on since January, and every update seems to reset my disc, This time it wasn’t loadouts and armor but something that requires more effort, I hope you guys look into this issue.
