Currently, castle moves are available even when the either or both pieces moved previously. This shouldn't be allowed.

Suggested implementation:
Keep 4 flags:

WhiteSmallCastleAvailable
WhiteBigCastleAvailable
BlackSmallCastleAvailable
BlackBigCastleAvailable

Initially all 4 flags are on, but turned off in the following cases:

when corresponding pieces move
when corresponding pieces are taken

Object move also needs these 4 flags to update the chess position with.
