@wolyn in the last one, I noticed the game acts as if the queen and knight never existed. 3.Rfxf8+ was considered illegal, likely because it assumes the rook will "jump over the invisible knight."
Bug Reports

Game #74632767 ended in a threefold repetition, and PGN4 lists the result as 12-12. However, my winning streak in the arena has continued, and the archive filters it as a won game.

On move 15, black promotes to rook, and for some reason, it is not possible for me to capture the rook through en passant, but shouldn't it be a legal move?

because if you promote and then immediately after get captured in a variant with points, you only get 1 point

Two mysterious bugs occurred here, yellow was not allowed to play 3.y Nd2, and later 10.y Gf6
Sometimes, in today’s WoF tournament, Blue is automatically moved for without the player doing anything. Example:

I wanted to play Exl10, but instead the server didn’t wait for me and did not fulfill my wishes by playing 1.b Exm13?. I still was victorious, but that move could have sent me off course!
No one has looked into this bug for a month? I have an explanation: if the page is laggy, and your move comes right after a zombie's move, the server auto-moves for you on your first move, even if your move is one of the worst moves (aka it plays random moves). This bug is really annoying.
Now I'm even angrier.

The server moved my camel-rider "without permission." I planned to open with a normal sergeant move. It's been happening for a year -- when is the staff going to address this bug?

Notation bug
I played a 4-player chess game against @zetahh, @7AlexisB4 and @Zakiisback.
You can see a bug with the notation. 5...Nxh13 should be notated as Njxh13, because there was an option to capture the queen with 2 different knights. 12...Nh11 should be N12h11. 14...Rj14 should be Rkj14. 21...Nf10 should be Nhf10. When a player checkmates multiple players, then it should be notated with # rather than +#, except in Play for Mate games. The 1st checkmate should be #, 2nd should be +# and 3rd should be ++#. Improve the notation.

# means that the player either completed the checkmate net without attacking the king or captured the king or checkmated by claiming the hill #74862061
Castling with cricket (another feature or bug?)
