I was playing MW3 multiplayer in what must have had a hacker playing it it, because on respawn I spawned with the class of an M16 or something, the introductory one, when you just start playing, and I didn't have that selected. After a few times of that I quit that game and I noticed that all my rankings and everything were reset, like some game modes weren't accessible any more, things were locked, etc. I though a restart would fix it but it happened yesterday and it's still like that today? Can somebody fix it?
Let me know what ID information you need to make it happen.
