The yellow castle tiles have been blocking for as long as I can remember. Don't exactly know why they block, but they do. They can be used to make some pretty cool puzzles and stuff. maybe even mess with the player by showing some tiles on the board with showimg, setimgpart, and setimgvis. Play around with 'em. I don't think they're gonna be changed from blocking, so deal with it, or don't use 'em
