I have been disconnected from my games in an arena run TWICE now. The first time when I played a discovered minion from priests imbued hero power. The second time when I simply pressed the pries imbued hero power button.
Two separate games. Same arena run. The same thing happened. “you were disconnected from your game”, it never reconnected so I had to restart the game to be able to reconnect. But the second time this happened I couldn’t even reconnect. I just got a straight up loss on my run. And it was turn 4, I had full HP so there is no way I could’ve died.
