My current game is on patch 12/1 but I guess it will be the same on this version. AI building selections are bad! I can see it on my puppet cities. AI choses high yield buildings for what they need but the problem is they build very expensive new buildings first in a lot of cases. Why build the newest building in 20 turns when they also could build 5-10 old ( ancient to medival) buildings in the same time. The 5-10 old buildings would result in a lot more yields and quicker. For example when I annex some puppets in modern era I have to build some of the most important ancient buildings because they have not done so in the 250 turns they were my puppet already. Thats just stupid. Even worse when I have the Civilizing Mission policy and the +50% production buff is not used. This may be one of the main reasons the AI tends to fall behind in late game. Btw is this a bug? My hospitals dont show their food to science conversion yields in the city UI under science just like the agribusiness does under gold. Do I still get the science yields? It seems not.
