If this helps it's the second time this has happend to me, first time I was supposed to rank up but didn't and had to do it again. Both times this has happend I've had the award message in game, finished the match, started the next match and quit about 5 mins into play. Could this be why it has never registered? If so I will never play warhawk again as this should never happen.
