Hi!
First of all, I like your mod very much, I have been playing a couple of games with the first version, too.
Right now I am playing a game with the Germans, only some turns left to industrial age.
I noticed that the AI seems to have big problems with the pop cost of the settlers.
First, they only have small cities, several capitals are size 1 !.
Secondly, they probably can't handle that high pop cost when building: When I found embassies in several enemy cities I found that they often tried to build settlers with cities of very low size, which resulted in their building capacities being blockaded until the city reached size 5... seems like the AI is not smart enough to build other things until the city has grown sufficient (like a human player would).
It seems like this cripples the AI very much. Anyone else noticed that?
