How is it possible that in the tournament https://en.boardgamearena.com/#!tournament?id=13212 I play with a non-existent visitor-794960555 player?

Account deletion after entering the tournament.

I think what he means is, that he needs to be automatically put through to the next round of the tournament because the game can no longer take place.

I guess the game will just time-out, but it could be better. Upon account deletion BGA could perhaps automatically forfeit all of the current turn based games for that player.

I had a similar thing, but just a normal turn-based game. Doesn't matter too much, but I will always try and give my opponents more time than has been given, but if the player is not even there....
