There's a pattern I've noticed while attempting to set a conditional in Chess960: the position in which the program takes input concerning the conditional is always the position just before the first castling move. So if neither player had castled in the game, the conditional would work just fine, but if one or both players had castled, then the conditional would get funky and ask for move input in the position before the first castle.

i have also found one position were i cant castle. i thought you could castle in all positions of 960 am i wrong?
