Hello, I've been playing Anno 1602 and it appears that my settlers will not advance to citizens? I have over 30 tons of liquor, tobacco products (I even have 9 tons of spices) and both a tavern and a school. They are happy and there is nothing in their wants area. I also have 70 tons of tools and around 2k of gold. I'm losing money because of the vines and tobacco fields. What am I missing? Thanks!
