Happiness is used as a proxy for can join factions y/n.
When I added nerve stapled all faction attraction from the 5 biotrophies died.
This means that any pop that cannot experience happiness can not join a political faction... I have no bloody clue why that was written in as a check.
There also doesnt appear to be any specific rule that relates factions to happiness... So no clue how to get around this without giving machines happiness (which i'd rather not do) - "forced_happiness = yes " appears to be the effect, specifically.
