there is damage hack?

Yep that bug is got on all server , I was shooting 16million in 4-5 map (:
That bug was if you change your Conf ( Conf 1 to Conf 2 ) Your damage will increase by x2 time
I got rank Basic colonel from Major
But i banned 2 weeks later

damage hack does exist.

I've played in this server, and it's not a lag, maybe a bug.. But however, exist.. :)
