Timer countdown warning sound

Two minutes ago I lost my game http://online-go.com/game/756055 by timeout. The voice countdown had just said “four”. This is MAJOR bug. If the voice countdown cannot be trusted it’s useless. I probably have under 1 second lag to the server. Four or Three seconds is out of the question. Also it immeaditly said I lost on time. It didn’t wait for the countdown to finish.

Edit: It immeaditly said “Error processing move” when I placed my stone while having around 3 seconds left in the clock.
The error persisted on the screen and it seems I had lost on time before my move.
