No, he didn't. It was a desynchronisation.
Game should be replayed. If Guerreiro gets below 88 points, then lo0ser wins, if Lo0ser gets below 10 points, Guerreiro wins.
Since Lo0ser was leading so much, it's Guerreiro's responsibility to get the game played. The game stays until you replay it. If Lo0ser refuses to play, take a screenshot of that and send it to me. I'll void the game then.
