Bug : I received the wrong message, i.e. Error, instead of the foe message while trying to join one game. The error persist after several trials.
I was in game finder and researched for all game with 12 players.
I tried to join this Game 13161262 and receive the message : Error No matching games found.
When I researched this game specifically using game finder and tried to join again, I received message like I am the foe on someone on the game.
