I was just about to win, when the board became unresponsive. I still had a solid WiFi connection, and could chat to my opponent about it: but clicking on pieces got no response. I tried backing out of the game and back in by various routes, for 10 minutes as my click ticked down. Then accepted a draw instead of a loss on time.
