Finished a Custom Game with a friend and my game would not return to the lobby. Had to restart. Finished the first Daily, stuck on initializing lobby. Had to restart.
And again after finishing the second daily skirmish. Not had a game where I haven't had to restart afterwards. Always "Initializing Lobby".
Finished Shattered Peaks walkthrough. Initializing Lobby I'll stop posting now. Safe to say all my games require a restart.
