Been having this problem since Sunday. Whenever I do ANY sort of gameplay while online, the game freezes then sends me to the dashboard. I’ve tried campaign, custom games, matchmaking, and even viewing games in Theater. I’ve uninstalled/reinstalled the game twice, all with the same results. Approximately 30-45 seconds into a game, it crashes.
However, when I took my console offline, I was able to play the campaign no problem. So the only thing I’m able to do right now is offline campaign, which wouldn’t be a problem considering I haven’t beaten them yet, except that none of my achievements will register until I come back online. And I’m not even sure if they’ll unlock with all the other issues that achievements have been having.
Please get this fixed soon.
