Board Game Arena

When I try to start a game in Arena mode, I get "Unexpected error: Solo mode for this game can only be played in Training mode". Clicking on the gear shows that it's set to play with only one player, and it won't let me change it.

Updated this bug as others have: https://boardgamearena.com/bug?id=43687

This was a configuration mistake... sorry about that, it should be good now.
