When I came across already formed villages they had a normal amount of farmers but when I created my own I can't get any to spawn. I must have over 30 villagers now and no farmers. I've tried killing them off and the new ones just come out to be the same. Low on shepherds and fisherman too but at least I get some. It's mostly cartographers, librarians, and clerics. None of the zombie villagers ever turn out to be farmers either. So many crops.... no where to trade lol
