I've researched Mathematics and the description says:
Allows construction of Academies, very efficient research buildings
However, a season has now passed and the building still doesn't appear for construction at my bonfire. After researching Animal Husbandry the pastures didn't appear instantly either, but were there when I checked back a few minutes later.
I've also researched Mining but there are no mines available to build.
Are there any other requirements for the buildings to appear or am I doing something wrong?
