Both I and a few others seems to have by mistake and for my part probably some stupidity, dismantled buildings by mistake, since all it takes is a right click and an unfortunate leftclick in the wrong place and poof... gone.
So... would realy like to se a serious mindnumbing and awakening Confirmation Button "Are You Sure Bumbass??" before a dismantle of a construction is performed.
And upon that note, a recovery of at least some of the mats would be nice. I am sure that at least some parts would be usable again.
Thats me for now, will sure return for more nagging
