Okay, I'm not sure where to post this, but today during a Bring the GM event it specifically says "There will only be 4 rounds, if the player has already traded with the GM in any of the rounds, he will not be allowed to participate again." And then someone won twice? I'm not sure how to upload a screenshot, or else I would. I don't know if it's just me, but that seems like a clear contradiction of the rules.
