Mountain - can pave, can't stomp or terraform

[barra]

This includes the Mountain, Sandcliff and Snow biomes. A player can pave these terrains, but cannot perform any other landscaping, including stomping the paved tile down to the original surface.

Paving/stomping works fine in caves, so I assume it's a bug. A player cannot use Survey to raise or level these three terrains either, so while a player could pave and build something on these terrains it's unlikely. There might be a work around; I've seen a farm built on mountain terrain using dirt and plowing. I don't know how it was made and I haven't been able to reproduce it.

you could dig away/stomp pavement before i'm pretty sure (maybe the quarrying conflicts with it now)? i did notice then that paved snow tiles when removing pavement turn into the grey mountain terrain, but that actually seems more realistic so i never mentioned it.

edit: tested, you can still get rid of pavement on mountains using the dig action.

Not true of mountain proper I don't think, but probably true of quarry patches, snow, &c. Presently we can't use more than some number of tile types internally, which is why we have delayed better fixing of this.
