  3. Chess 960 castling bug

Hello,
It seems in Chess 960, you are not able to castle according to the rules.
Please look at Nakamura - Carlsen position:
nbbrqkrn/pppppppp/8/8/8/8/PPPPPPPP/NBBRQKRN w - - 0 1
Both side are able to castle short at the first move, according to Magnus Carlsen:

Indeed in Lichess it seem you are not able to castle if you have the rook in the destination square of the king.

Please look at these posts upon Chess960 Castling rules:

Please, can you fix it?

Have a nice day,
Thank you

Sorry,
it is a mistake by myself.
I have also to specify in the FEN position that castling is possible:
nbbrqkrn/pppppppp/8/8/8/8/PPPPPPPP/NBBRQKRN w KQkq - 0 1

So Lichess does the right think. It castles.

Sorry for my mistake.
Have a nice say

Have a nice day as well!
