They have two settlers (had one for quite a while now) and are so far focusing mainly on military strength. What should I expect from them - are they waiting for something before settling? Is this settler stockpiling a normal thing? I usually don't team with an AI so I haven't observed this before.
Update:
So they stocked up 7 warriors (notice how they are the only ones on the island besides a city state - you may not be able to see it completely but I later explored it) and got a 3rd settler. That 3rd settler they finally settled. They are still stockpiling 2 settlers and are way overcompensating military might. I am still baffled by this AI.
Additional info:
It is a mod game with [BNW] Mass Effect Civilizations enabled. There is no mention of any AI tweaks so my understanding is that even though it is a modded civilization, it is still using vanilla AI. The AI in question is the Ranchi Civilization.
