[bug report] Finished game's clock still ticking down

I finished a correspondence game about two days ago, I was checkmated. Today I got a notification saying my time was running out on that game and that I was about to lose.

The game is over, I've lost ELO and my opponent won theirs already, but it's still counting down and asking me to move (which of course I can't)

I have images, is there a way to post them here? thanks
