Auto-DC when dreadlich tamsin draws into fatigue

Twice now, my opponent has played Dreadlich Tamsin and drew into fatigue, and both times immediately I disconnected from the match, and upon relaunching the game it would bring me back into the match, work for about three seconds and then disconnect me again, repeatedly. This is on PC.

I drew into fatigue for lethal as dreadlich tamsin while rope was ending and animations still playing after having completed the warlock quest and played it’s ending reward. I dc’ed and the hero power action never went through. When connecting back into the game, hero power was showing as used but did not generate another minion or trigger the fatigue damage.
