I played a move, but it still showed that it was my turn to play. However, my opponent’s timer decreased. When my opponent’s time ran out, the game timed out… and I lost on time.
Interesting, I’ll look into it, sorry that happened 
A similar thing happened to me. http://online-go.com/game/732568 I was black, I made my move, and it was white’s turn to move. White never moved but the system said white won by timeout, which makes no sense.
