This happened to me during a draft (and a few other times in constructed). It was really annoying because I was definitely about to win the match in the turn I randomly lost, and I wasn't using any timers and I was quick in responding and engaging in the match. I was less than ten seconds into my turn when I just randomly lost. It's especially terrible when it happens during a limited event that you used gems or gold on.
