As I understand it, there are three ways to teleport. From Boston to homestead, from homestead to Boston, and from anywhere to homestead or Boston as long as your inventory is empty.
Well, I can do the first two, but I can't teleport with empty inventory. I've tried filling my inventory with sticks and dropping them, but it still seems to think I'm carrying something. I've also tried getting KOed, which did send me home, but the bug is still there. I've heard a few other people complain of this as well.
