Exiting room to lobby closes game

Hey Guys!

So with the new update I've noticed that every time I try to leave a room to exit to the lobby. The entire game crashes and closes. Any ideas to try to fix this or is this a client problem of some sort?

EDIT:

So when exiting rooms, going to game room before exiting to lobby works just fine; however, exiting to the lobby causes the game to crash.

Thanks!
