Well it's complicated, and we have to run tests. But the major workround is through the tech tree. We use autonomies lockdown scripts for most factions but the simple homeland, autonomy, colony categories don't apply to the Italian factions. One of the buildings in the tech tree will be 'capital' which represents the settlement being a city-state, which for your faction will make it very rich and of a very high level of recruitment etc but if it is not your faction capital the settlement with a 'capital' building will be likely to rebel since it represents a rival within your faction. lol, I can't really explain it very well but I have tried to do this in earlier previews. I might just be tired, it's 2AM here and I've been mixing wine with White Russian.
