I have begun working on a map and I don't quite think I'm doing the floor correctly. To make the shape more natural, I connected a bunch of blocks together. When it came time to convert them into displacements to get a more natural ground, however, I ran into a few problems. What I encountered was that I cannot sew the displacements together, and that my changes don't show up when I compile and test the map. I'm not quite sure what I've done wrong, so help would be appreciated. Screenshots can be provided when need be.
