Smooth Floor vs. Stone Tile Floor

[Sokar408]

I'd prefer no bonuses for smoothed ground at all, but that it was needed before you could lay carpets or other flooring from stone, wood or metal on the top of it. That would be a great way of making cave bases even more work intensive and a harder choice, without ruining the natural benefits mountain bases should still have.

I second that. Also I have noticed (this might be a bug), that I rip down walls inside a mountain, to build my own (so I don't have cables running through the hall ways), if I don't smooth the floor before building the walls, the wall area gives a minus -2 beauty. Is this intended?
