Not able to castle in 960

In game lichess.org/6Z9FE5TZbFB3 I was not able to castle after move 15. Tried it on 16 and 17 and some later moves. King doesnt even have to move there and isnt threatened.

I think I figured it out, when I took board editor, it showed that 0-0 for white and black where disabled.
Idk why tho
Kingside castling should have been possible in that game, as in any game with a legal 960 starting position. The FEN of the starting position is not correct according to chess960 rules. Our developers have been are aware of this and we are checking what was going on.
Hello, thanks for the report we have identified the issue and hopefully will be solved by tomorrow.
Hello, we deployed the fix for this in production this morning. The bug happen when you rematching chess960 for at least 2 times. After that the castling config will be incorrect. Sorry for the inconvenient (I created the bug)
