Campaign and Multiplayer Shields Gone

Yesterday, I signed into Xbox LIVE while going on Halo 3 and my campaign was wiped for no reason. My shield in the menu was blank and everything. I don’t really play the campaign so I said oh whatever. Played multiplayer, everything was fine. I go on today and my multiplayer shields are gone but it still tells me the correct amount of games I’ve played, like Ranked and Social games amassed. My rank is also correct. I go on here and my stats are wiped too for Halo 3. To add, I can’t play online because I get the “information can’t be sent to the servers” or whatever. Someone please help out. Thanks.

From what I’m gathering, there are some server issues with Halo 3 today. Try again tomorrow and see if it’s fixed then.
