No, it did not. Unless you mean the PREVIOUS deck won while I was making a new one and the winnings are added to the new deck. Current deck still has 0 games.
I did find, though, that the deck was placed on a different ranking on the leaderboard than it said in the menu.
I agree this is something else, thought I'd just mention it since it falls under 'Arena Weirdness', thought it might help to have as many clues about errors as possible.
I won't push this point further as on general grounds you are probably right that this is not related:)
