'Ello peeps!
When watching Sacriel(twitch.tv/sacriel (http://twitch.tv/sacriel) play RimWorld (AWESOME game, btw.) he build a room in the rock wall. There's rubble on the ground that does indeed need cleaning. On top of that he build hydro tables (The ones where you can grow food on REALLY fast.). When building carpet under the hydro tables it deleted the plants that were on the table.
Hope I explained it good enough. I'll see if I can make a highlight of it.
