How do I get leather...? I have a tannery, I guess I need a tanner, but I don't know how to get one... "Tanner: 0", "Hunter: 0", etc, have little icons next to them, but clicking does nothing... I've maxed out my village etc (and am accumulating huge quantities of wood I can't use for anything anymore), but can't seem to advance until I get some leather!
