I made the last move but my time was still running

It was a misterious bug during my last game. I could't do anything because Lichess-server said it's not my move but my time was still running. Afer I lost my game with timeout I checked all moves with the analysis board but my last move was not on the list.
I hope this bug will not come again.

Has someone seen a bug like this too?

Yes, you have to reload the page.
