It might work with modded federation types. This mod modifies just the factions themselves. The modded federation would need to set the required laws: centralization low or minimal, and separate treaties allowed.

does this at all work with modded in federation types or only base game? As I'm running with a modded federation type that still gives me the modifier so I'm not sure if another mod is interfering or if it only applies to normal federations

thank you

Thank you for this! :)
