Hello! release 0.C Build 3079
I can not understand why the nails tucked in NailGun not considered and therefore is there for a lot of things can not be made if the nails are loaded in NailGun. to build something has to discharge NailGun and then - the game (suddenly !!!) see these nails!!!
hocus pocus 
I can not remember the error in earlier release of the game (although my memory is full of holes, but it is a fact that I would really like something, but it would have already noticed)
