Problems with human AI

[Henry_AC]

Hello, these days I have noticed a detail in my map that I am creating (altered body, I have not touched the AI melee that comes by default). It turns out that human AI does not always develop, it only builds the main buildings (barracks, smithy, sawmill, farms) and basic units (peasants, heroes, soldiers, riflemen) after killing a few hackles, it does nothing, just it remains at the base or attacks an enemy base but very rarely. I did a test (all human) and of the 8 only 2 were fully developed. Does anyone know why this happens?

I use version 1.31
