Reproduction:

Turfs in many cases do not properly store baseturfs, lavaland syndicate base reveals space when its tiles are destroyed, as opposed to lava as it should, all jungle turfs share this issue, occasionally both in space, on whitesands, and possibly other planets, removal of a wall or turf results in an error turf appearing in its place, resulting in quite a lot of messes that need to be buildmoded away.
