So here's the deal:
This already happened to many people not only me, and not only in cw, but in tdms aswell.
The bug is that sometimes you get enemy " -- " ping, probably cause NAT not working well or something, but the worst part is that he's able to kill everybody and we cant see him.
Hope you guys take action on this soon since its really annoying and there's some players who're abusing it, as well as others who get frustrated cause they cant play properly.
Thanks, Matt.
