Alright, so I talked to Viper and we decided that the round will count for now, since Viper also didn't really think about the alt/main stuff. DoctorGold advances into the next round.
However, FistOfLife your main account is just simply not registered for the event, so you'll play the rest on your alt DoctorGold. Something else won't be tolerated and you'll have to re-do the matches if this comes up again in the following rounds.
Sorry for the inconvenience, especially to Dragon.
