PDX hasn't fully implemented this system – modifiers for building slots have absolutely no effect.
The current implementation is essentially a half-finished framework.

MY SUPER CAPITALS SHALL RISE AGAIN.

THANK YOU FOR THIS MOD DEAR MOD CREATOR!

Critical question... Is there a way to create a system like the previous UIO slots mod, so you can open the slots by time and with technologies/decisions? Because I feel more than a normal amount of slots all free in the beginning will cause the AI to just spam gazillions of these buildings, drop lag, and destroy their economies.
