My oponnent played The Scourge and then a mage secret, after that my game just lagged and stopped working, so i just quit and fast launch it again, when the game started i saw that i am already lost but only 20 seconds have passed, i have a video record of that moment if you need
I’m guessing that you didn’t lose due to the quit/disconnect; your opponent was able to just … straight up kill you. A board full of random big undead minions will do that, don’tcha know. Maybe one of them had Charge?
And if they played The Scourge (9 mana) plus a mage secret (3 mana), then who knows what else they might have been able to play. Maybe they just Fireballed you to death?
I don’t understand what actual bug you are reporting here.
Did you force close the app or quit using the quit button in the menu?
