I encountered a bug tonight where my opponent's timer ran out while deciding whether or not to keep their hand. I waited until the timer 'rope' appeared and then until it reached it's end, instead of resulting in a loss for them the timer remained sparkling at it's end. I left the game open for a few minutes and nothing happened; when I closed and re-opened the game I had received an additional loss in my draft (Arena Cube Best of One). Attached is a screenshot of a video I took. I'm happy to send the full video via email, for some reason .MOV files are not supported through your file attachment system.
