Hi ! There is a problem on the sharegame multiplayer games. I created a multiplayer game in sharegame, my friend "pounet" can connect to it. I leave the game and my friend stays. When he disconnects, the datas are saved/sent. I try to reconnect without my friend, it doesn't work... I have this message on screen : (it's a french account sorry :-)) If i click on "no", it doesn't connect me to the game, if i click on "yes", we lose all saved datas and we start...
