With this mod, leaders now get traits made on for leaders rather than minister traits. However, you should note that these properties appear only after one round, after the new leaders and ministers have appeared. Install: Faction_Leader_Trait.pack -> Steam\steamapps\common\Empire Total War\data
Known problems: Some traits that should be mutually exclusive still occur together. For example: Not Religious and Divine Right to Rule
Does it work with major overhaul mods like Darthmod, Imperial Destroyer, etc ?
I have only tested it with Darthmod so far and it worked without any problems.
