I’m playing Vashj, there’s a Deathwing in the game. I faced him during the 2nd round, lost. I had a 4/2 water droplet (buffed by Relics of the Deep turn 1), and it became 6/2 with All Will Burn. However, when the turn ended, All Will Burn was still active on the droplet, and it’s been active ever since (currently on round 6).
Just reporting this glitch. The droplet kept the Deathwing buff.
