Castling disallowed bug

I found a new bug. I tried castling long, when my opponent was covering a square that the rook would pass through but the king wouldn't pass through. It wouldn't allow me to make the move. As soon as I covered the line to that square with my knight it allowed me to castle long. Needs to be fixed thanks!

Screenshot?

was in the middle of a game, didnt get one

I forgot! That's happened to me, and there was absolutely nothing that should have stopped me! Then like 2 moves later I was able to castle short after I moved a few pieces out of the way.

Ahh yes apparently I got the rules for castling wrong. "You can't castle through check" means the king can't pass an attacked square but a rook can. Funny how I've been playing chess so long and never realized this.

Fix will be live within a few hours.

Great, thanks!

The rule became very lenient.

Yesterday I made a screenshot:

Green followed and he castled (0-0) so crossed over the n6 square in which it was in check.
