Standard way to change relations between factions is in the campaign_cultural_relations_table


Some changes made do not appear in-game for certain sub-factions




For example:
Giving empire a diplomatic affinity of 10 to other empire factions in campaign_cultural_relations_table = empire factions have +10 diplomatic affinity towards each other


However, one or two empire sub-factions do not receive this change and instead hate each other. Why? and how do I change this?
