Rather curiously, if I designate a muddy tile for Smoothing but don't actually enable Stone Detailing on any dwarf, a random dwarf with Cleaning will come along and clear away the mud from the tile and any surrounding tiles. Somewhat interestingly, the old 2D version behaved the same way, though that one only cleared mud from the specific tile, not any of the surrounding tiles. --Quietust 16:06, 21 August 2010 (UTC)
Using up stone?
I've noticed that if I designate someone to smooth a floor that has a stone resting on top of it, the stone is no longer there once the floor is smoothed, is the stone being used in the smoothing process? – unsigned comment by Twilightdusk
