Changes

Mining the floor or ceiling of a cave does not create tunnels. Instead, it raises (for ceiling) or lowers (for floors) the cave. Note that as with [[digging]], these actions affect the closest corner of the tile, and not the tile itself. A ceiling tile can be mined upward approximately 40-50 times before it is too high to reach. A floor tile can be mined downward a maximum of ?? times. Excavating a new tile from a tile that has raised ceiling or lowered floor does not open at those levels. The new tile will be standard hight height with the the ceiling and floor sloping as appropriate.
