In my current game as Augustus I'm now in the exploration age. Throughout my run I noticed something weird. During antiquities I played as Greece and I noticed I could only buy one of my special buildings, the option to build the second one to complete the quarter was always greyed out even if I had the free slot and enough gold.
During the age of exploration I went with the Normans and again I came across the same issue (see picture below). Anyone know why I'm having this issue?
