I played a game right after and the same problem occurred. I cast Brackish Blunder on my opponent's attacking tapped Bloodrage Mycoid. The Bloodrage Mycoid did no combat damage to me, I got a map token, but the creature did not return to my opponent's hand. Then they cast another copy of Bloodrage Mycoid. I suspect the bug created a duplicate in their hand (or it is a crazy coincidence to happen 2x in a row just like this).
I would like a refund for this event. The card I drafted is unplayable and ruined my games.
