Opponent conceded while MTGA was putting trigger on the stack; I can't exit match.
Using:PC, Windows 10
My opponent conceded as my Sokenzan Smelter's ability triggered, but before it let me pay the 1. They auto-passed priority in response to my other triggers, so they did not concede while holding priority. They conceded as MTGA was putting the trigger on the stack, and the VICTORY screen never showed up to let me exit the match. I have had similar things happen a few times before.
Side note: This also messed with Untapped.gg because it couldn't read my rank after the game.
