Well, dunno if others have the same problem, but I'm on lvl 16 and need to beat Slavam. I went to the challenge page via the "click here" link and lost, after that I clicked the "fight this opponent again!" and won after the 2nd try - but it doesn't count for the quest =/

Anyone the same problem?

thanks a lot, I'll try to score another win against Slavam then =)
