Mate not recognised

In this game black is mated but the game is still going , Black's clock is still running , this is the 1st time I've seen something like this

@AayushGhate maybe lichess is down because every single game was deleted or something.
I thought it was my wifi because imgur was also lagging.

same to me. lichess.org/scR7srckycaB

aayush because it is some problem in lichess see the tournament page 3 round everyone has got half point (those games going on)
