Turn off the auto-concede! There were around 500 triggers on the stack, including life gain which would then trigger ajani´s pridemate to get a counter, so the stack took a couple of minutes to resolve. Then, when the stack was completely resolved and I would go to combat to take the win, the game auto-conceded me resulting in a defeat. Unacceptable.

I understand we the need for the auto-concede when it comes to inactive players, but waiting for a stack to resolve does not equal inactivity.
