GM glitch, Thats how GM observe the match.....
I once lagged at the log in and loaded on the opposite team...It was a clan war.
Something weird happened to me while I was using my hacks in Quarantine mode.. I had joined the round too late because I lagged in the loading screen so I was in spectator mode. But apparently I got chosen for the host or something because it showed these zombie ands that floated and showed me having zombie hands too.. wtf?
Someone made a thread a long time ago about the lagging onto the wrong side of a clanwar thing
This is just a glitch that happens occasionally
