Recently i have experienced several times that the game will get stuck randomly in multiplayer. Often it happens when i concede while some animation is playing (fx from passing the turn). But sometimes it doesn't have anything to do with me conceding (might be the opponent conceding). Below is an image of the most recent time it happened. The game got stuck but the timer kept running for my opponent. When the time expired nothing happened.
Up. This is still happening a lot if i concede while something is happening. And it's happening on different computers as well.
Same thing. Opponent AFKed as soon as I had a winning position, sorted email for 15 minutes while the clock ran down, time expired but no game end, and then I logged back in for no notification of who won or lost the match.
