Memo3 was playing on EU_2 siege and was on defend, well he opened front gates (let big posse in) and then he teamswapped. He's excuse was "sh*t it was bugged i couldn't close the door" and excuse for team change "i got stuck in bugged water had to change teams".
Seems like he was cooperating with attacking side of the game all the time, and deserves a nice few days cooldown so he next time thinks what is defending and what is helping attack.
