To be clear, the one I'm talking about is "Acclimatization of Will"
"Enemy Allegiance Rate Change >25% >50%"
"Prophets of the Unity go on pilgrimages to the planets under their culture's influence to spread their message, increasing the change in allegiance."
How exactly does that translate to just more generic culture production? If that's how it's suppose to work then why doesn't its description just say something about more culture? It seems to very clearly be meant to increase allegiance change rates to allow the advent to enact culture victories on enemy planets faster, which is a very nice utility for the loyalists, but as I said it isn't doing this, or anything else that I can see.
I went back and tested it and I didn't see a change in the culture production rate of my own worlds after researching it either.
What exactly is this tech doing?
