Hi Blizzard!
I just encountered an interesting bug. I played a Naga to upgrade my Barbed Nets. I used this to first target an enemy minion, after which I wanted to target the enemy Hero. Clicking however did nothing, only showing the “Squelch/Unsquelch” prompt. I even quit out but upon reconnecting to my game everything was locked, I couldn’t even end the turn.
Noteworthy things; There was only 1 enemy minion which wouldn’t have died after casting Barbed Nets on it. I was playing on mobile (Samsung Galaxy S20).
