I've been searching the Hiergamenon, but I believe that not all entries have actually been elaborated upon in 1.3.
I realize some structures need certain types of upgrades to build, and others need certain types of terrain to build. But I'm not sure I entirely understand all of them (and it would be nice if at least some of this could be added to the Hiergamenonenen.)
I have a town next to a river, which I would have imagined, as a source of fresh water, is the prerequisite to building a well. But I can't build one. Is there a list somewhere?
