How to force AI build certain improvements? I have 4 separate culture-specific small wonders which autoproduce settlers. Shield cost is set to 0, so they can be built in a single turn. They all have some additional bonus (double strength against barbs, healing at an enemy territory, etc.) and produce some culture. Out of 16 civs, only 2 build this SW at the start of the game. They belong to different cultures and share nothing in common - neither civ traits, nor building preferences. I have no idea, why they do it, and other civs simply prefere to spam workers and basic combat units. I removed all "build often" flags for units for all the civs, tried to play with civ traits and flavour - to no avail. AI simply refuses to construct that wonder, except 2 civs which have nothing in common. I even checked other mods with similar mechanics, but it didn't help much either.
I have no idea at this point, really. Can anyone, please, help with that?
