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 around 31 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 height with the the ceiling and floor sloping as appropriate.
