The problem lies in castling not being supported in the "Quick mode" of conditional moving. Same for en passent.
Try using the "Deep Mode". And tell us if it works, hey?
Yes, I utilse deep mode whenever castling..you have to move both the K and R individually..I assume this works as I've made many such moves and I think I'd have noticed by now if the game was returned to me needing the moves to be made again, those that I have in my in game notebook.
