Bug with game completion today between 7:24 and 8:04

This morning at 7:24AM UTC, a lichess update was rolled out, that contained a bug with games completing in checkmate or stalemate.
These games did not complete correctly, and eventually the checkmated or stalemated player would lose on time.
A bugfix was immediately developed, and deployed on lichess at 8:04AM UTC. Since then, games are completing correctly.
28k games that completed with a clock flag between 7:24 and 8:04 were removed from the database.
Sorry for the mess. I made a mistake and I should have tested my code better before sending it online.
A list of the changes included in that update will soon be available on
I can't see my bug game yet!
