960 castling problem

There is a bug in 960 wrt castling. Please see the game http://en.lichess.org/AmSFvToRLwe4

According to the rules, e.g.
support.chess.com/customer/portal/articles/1444897-how-do-i-castle-in-a-chess960-game-
White can castle with the king afterwards on c1 and the rook on d1. Of course White can also move Kc1 here. Lichess won't let me castle and always moves Kc1 when I click d1+c1, no castling offered.

What am I missing?

You're missing that there's no way for the pc to discern what you're trying to do. You could also try to simply move your king to c1. In this case try clicking on your king, then the rook.

Ah ok thanks. Resolved. But when queening a pawn you're offered choices too, so this would be a feature request.

Or even better, you could display one of those move hint points ON THE ROOK.

Agreed - this has led to problems... see http://en.lichess.org/forum/lichess-feedback/turn-off-castling-when-clicking-the-king-then-clicking-a-rook#6

So it would be nice to have a choice
