Weird after-patch glitch...

I was in a game once before this current patch and that occured. Might be a hacker thing.

I can only confirm that it appeared to me once before the patch (I can't play CF anymore since its release anyway).
It appeared when I join a game. Black screen with HUD, my weapon was the XM1014, a weapon I strangely do not possess, the famous shotgun that glitched Alaska a while ago. Crossfire froze, I had to quit the game.
