I was just coming to post about this specifically. I've been building nails since last night and I just missed the boat. Now I have some 60 nails sitting in my storage that I won't use. Lol. It's a time thing and also a storage thing. 80 metal is easy to make, but with 180 max storage, I gotta dump some stuff to make room. The other sucky thing is that storage upgrade items take up storage space. The irony that I have to upgrade my storage so that I can hold storage upgrade mats. Wtf.
