0004520: Incomplete slopes in caverns
In the caverns of this fortress, there is some strange topography. Slopes apparently have the upper portion, but not the lower portion. See the screenshots below.

Ramps dug out by my dwarves function normally.

Save here: http://dffd.wimbli.com/file.php?id=4189 [^] (It's the same fort I've linked to in other issues).
I haven't the faintest what causes this, other than to try the worldgen settings listed below and see if it reoccurs.
The worldgen settings I've used to create this world follow.

The slope erosion bug (0004315) caused this kind of stuff.

Is the save from .23?

It's from .22, I think. I've upgraded several times early in the game.

Can we close this? I haven't seen this in the newer versions.
