/* Continuing dissassembly - work in progress
* Known bugs:
* Raising the corner of a piece of land doesn't remove walls.
* Small scenery elements (ones that take up 1/4 of a tile) are not removed when changing land height.
* Original bugs:
* Lowering the land tile underneath a wall removes the wall.
* Land can be raised over flat scenery items (gardens, for example) without removing them.
