im guessing you didnt save n quit before you shut off the xbox so it wouldnt remember you rented it out
i dont know about the black shith thing i only did it to get the 2 achievements maybe with each level blacksmith you earn its changes but i dont remember it doing that
ps its faster to make money buying up weapons from everywhere and selling them in fairfax the prices are always higher in fairfax so you almost always make
profit sell everything in fairfax!!! but watch out for the fairfax traders giving you discounts you could lose money that way so remember what you bought things for and what you sold them for ,once you get to the master weapons you can make 20 k a run. buy all the stores first for the best profit from rent
