I wouldn't know where else to post this, so I'll do it here. The Polish PpKR clan seems to be made up of troublemakers. This morning their members PpKR_Czerniec_Witold, PpKR_Czerniec_Szezypiork or something similar, and another of their members whose name I've forgotten, together with a Tatar player named Mysyk or something along those lines decided to annoy the rest of us players with their glitching and trolling.
First, on the invasion server, Witold refused to participate seriously and fired a grapple-loaded cannon into the rest of his team. He also used some sort of bug where he would drop his firearm, quickly switch weapons and pick it up again to reload it swiftly. Later he continued to use this glitch in battle mode. Not to mention the four of them repeatedly exploited glitches to go through walls and houses to sneak up on us.
