Okie I used the pixel dissplacement and I found out when I put the turf on another turf when I play the game that whole section moves and not just that one turf is this a bug?
Fact is, there can only be one turf in a square. If you add another turf through the editor, any turfs below it become underlays. If you want to have two things in a square that act differently, make one a turf, and the rest objects or mobs.

So no, its not a bug.
