[CLIENT] Unable to start a game.

Either way if I was solo in Queue, or duo, I was unable to see that I started the game... After pressing "Find Match", it says "Players are not ready", even tho I'm the only one in the lobby... When I invite a friend, and he joins, I don't see him in a lobby with me, untill I click "Find Match", when I click on the "Find Match" button my friend appears in the lobby, but it again says "Players are not ready" (for me), but it normaly starts for my friend (He sees the accept/decline buttons, while I don't)... I firstly tried restarting the client (which didn't help), than reinstalling the game (didn't help either). I tried with a custom game, which started normaly, but than got stuck on 0, when timer went out, just before the game is about to start... Finally got in a custom game after restarting the client and automatically reconnecting to the custom game...
