I've encountered several bugs:
The most annoying is a totally broken underbarrel grenade launcher animation. Since the last patch, the grenade launcher is kinda floating in the air and you can't even aim with it, as well as there is no reloading animation.
The second thing is a disappearing shooting sound in full auto.
The third is a wrong end match statistics. For example, I've killed 10 people and died 5 times, but it could be depicted that I killed 9 and died 5 times. Sometimes when I even didn't appear on the map and the match was over, it could be written that I had killed several times.
And i really hope to see Summit, Crossing really soon!
