Last night one of my team mates and I are at the Northeastern airfield. We are in the most west building next to the ATC. After entering the building my partner and I did a through clearing of the building. I proceeded to cover the door concealed by the corner of the wall at the base of the stairs and my teammate located in the 1st floor hall just behind the stairs accessing his gear. The next thing we know we are both unconscious, no shots fired and no typical "Login Reload" sounds. So now I'm pissed, I can hear a players movements around me, I figured probably looting my gear, the sneaky little bastard, lol!. Then the next thing I know, I'm coming to and the sneaky little bastard is running around "glitch" halfway in the floor in front of me, where I proceeded to empty my 30 round clip through the back of his head!! Revenge is sooo SWEET! :) My question is, is there any KNOWN "bug/glitch" that lets someone access the buildings somehow through the walls?
