played a match in an unranked server today. i quit the game by closing it. then later on when i go back in again i see under leaderboard my kills are at 0 and my deaths are at 0. everything is at 0 even the time spent in multiplayer is at 0. now i was able to keep all my xp and unlocked weapons and my level is at the right #, but all of my stats are at 0 like i have never touched multiplayer before! please help!

Try ranked next time. I remeber this happened to me in the demo but so far it has not occured to me again. Also try looking through the forums because i think they already made a thread for a fix to this.
