An entire game was played and I checkmated but it glitched and it said that I did not move

I played a game and I checkmated my opponent. However, something strange happened and no points were awarded to either side and even though it said checkmate the score said 1/2-1/2. I thought the problem would eventually fix itself so I logged out, but after I logged back in it deleted the entire game and it said that white lost because I did not move. Here is the game: lichess.org/Poi1GiNMejP1 This was right after Lichess restarted so I suspect that has something to do with this.

Moral of the story: don't play when lichess announces it's restarting
