I updated MCC, restarted my Xbox and everything seemed to be working fine. But then I noticed I met the requirements for two challenges (10 missions in co-op and finishing a matchmaking game with a streak of 7 or more). The status bars were full and the data showed I got the challenge, but it never popped. So I logged out and back in and what do you know…things were reset to what I had before I started playing today. And it wasn’t even all of the challenges. Some reset to 0, others had some data save but not all of it. At least with the old bug, we could see when we needed to log out and sign back in. But now it looks like you’ll never know for sure. I appreciate all the work 343 is doing, I really do. But this is beyond frustrating. I probably one mission away from completing four challenges. Now I have to restart. Anyone else having this issue?
Same thing happened here. Did it ever sort out for you?
