In Game freezing

[machavelli]

Is anyone else still having there game freeze up in the middle of a match and than dropping you from the game.  It happened 2 times last night out of 5 matches I played.  The second question i have is the wingman sometimes hasn't been registering hits, I have sneaked up on a few enemies stood right behind them with sites and shot and no damage was done they turn around and killed me, have had that happen a few times now.
