I was playing against a questline deck and ran into a problem that resulted in me just giving up and conceding the game.
I think what happened is I was looking at my opponent’s questline while he completed step 1. Because of this, step 1 of the quest STAYED on my screen for THE REST OF THE GAME.
It gave me an unfair disadvantage (could not target most minions, could not see what discover options I picked) and eventually I conceded out of frustration.
I even got a screen cap of this, but idk how to upload pics.
