Just finished the second round of my first game in a new series, 1-1. My opponent then disappeared a message appeared to confirm that they had disconnected. After a bit of a pause the game left the match and I was surprised that I had been given a loss and my disconnected opponent had been given the victory and his 3 points go along with it.
I'm not too fussed as I never get too far in these tournaments anyways (I don't play cent) but I would of thought that the disconnecting player would of forfeit the match, not been given a victory.
