So I build an enclosure, seal and lock it, and build a few structures in it. Finally I erect a Smelter in the center. I smelt a few bars with it, then go to bed, planning on deeding the enclosure tomorrow.
I log in this evening to find the smelter GONE. All the other structures are there, and the gates are intact, so what gives? Do smelters really decay that quickly on un-deeded territory? And how could I have seen some indication that it was decaying so rapidly?
