I just had exactly the same issue Emorejets!
Got to 39 at the end of a level lobby. But it didn't seem to update properly. No bar movement no messages etc.
Went to the customize screen and it was all * and the padlocks were gone but no unlock options!
Played another level and it said I was promoted at the top when I launched. Go back after and still no difference.
So is this normal or a bug?
Please don't tell me I have to keep on to get the unlock as that will take ages. Plus have to get C4 too.
I want my Gauss Rifle!!

#Azrail Aleback The way the game works is really bad. To update your account you have to quit in the game or at the end, So if you get kicked say 3 games from now all that work is gone. (3 games on 1 server with out quiting)
Though I'm not sure if all of it is gone so say, you unlock a Dogtag in a lobby, if you get kicked or something like that. You will lose it, Best things to do now is, Play on EA's servers.. quit at the end of games or mid game and pray for the best
