I just got on Halo 4 today and was going to get online, but I got an introduction to war games and messages I have received before. I am SR-22 and my level didn’t get reset but everything else did. Everything was back to default. I wasn’t mad because I just put everything back the way it was before then. What did make me mad, though, was that I completed the campaign, but all of my missions were reset. I resumed campaign and completed the last mission, but all it says is that I have the prologue, last mission, and epilogue completed. All of the other missions say that they’re locked and that I haven’t completed them. I have the achievement to prove I completed the game. If anybody knows how to fix this, please contact me immediately!
