If a player pauses the game right as a victory condition is met the game stays paused and cannot be unpaused. This results in a stalemate where both players must leave the game. Tested this in a custom game after it was used on me in a ranked game, 15 minutes passed with nothing happening. No matter what I do I cannot unpause the game.
This is a gamebreaking bug and can be used by any player to prevent a loss. It is not difficult to execute. Please address this quickly.
