Lost tournament game I didn't play?!?!

I just played in a lichess hourly blitz and lost a game vs. muratti that I didn't even play in. I was never notified of the match, never saw a board, never made a single move, and yet i got credited for a loss!

Please fix this!!

same with me in bullet

Seems like a good site in general, but I think all sites have errors once in a while. Hopefully it does not happen to either of you again.
