i'm trying to make faction-specific units just for the hell of it. i've done it many a-time from Medieval through Shogun. i found what the game is calling the new ROTS clans under factions, but when i add an entry in units_to_exclusive_factions_permissions like i would normally do, it seems to have no effect. the unit i created is recruitable by all clans even though there's a gem_minamoto_kamakura - true entry in exclusive_factions.
i figured this might have ramifications for real modders and wanted to know if anyone else has encountered this.
