I need some help with my game id: 85977. I want to make a castle
(the best move possible) but I'm not allowed to. The thing is that I
know that I'm allowed to make this move. I never moved my king or
my tower, my king is not check, and it won't be if i make the castle.
So this is a major bug! Is this happened to somebody else? Or maybe
I missed something....

but you had already moved your king to take the white bishop........

LOL! Yes it's true.... I've just forgot this move! Thank you GrayKnight
for wake me up!
