I'm not sure if it counts as a bug but when confederated unlike in game 2 where Morathi spreads "Own Faction Corruption" when confederated she only ever spreads "Slaanesh Corruption" leading to her imposing enormous negative effects on any region shes in and causes attrition to all other armies in your faction.
this feature/bug makes it an enormous liability to confederate her as any other Dark Elf and feels really bad.
