So I’ve decided to focus my first few games on the Delhi Sultanate and have been achieve the first mastery, which is to increase the yield of 6 berry bushes. This is accomplished by building a mill next to said bushes, however it does not seem to work, as I’ve yet to get the mastery. Do I have to win said game or do something else to get the mastery to register or is it just a bug.
I got it no issues. Did you build the mill before reaching Age II? It is a requirement for the mastery.
