woops... preety sure they were supposed to fix that when they fixed the reanimation flagship thing...

Nope

• Advent
• Fixed phase missile block on Advent culture techs to give proper (positive) buff.
• Removed 'minelayer' role type from Advent carrier cruisers to prevent them from building squadrons of useless homing mines.
• Advent Loyalist
• Updated Subjugating Assault ability on Coronata titan to no longer fail if the player doesn't have enough fleet supply.
• Added target constraint to Domination and Subjugating Assault abilities to prevent Flagships and other non-controllable vessels from being affected.
• Fixed a bug that caused Coward's Submission research ability to always lose the chance roll to convert.
• Advent Rebel
• Purification ability (Eradica titan) antimatter cost reduced from 80/80/80/80 to 65/60/55/50.
• Strength of the Fallen ability (Eradica titan) duration increased from 60 to 120; range increased from 2000/2500/3000/3500 to 3500/4000/4500/5000.
• Increased conversion chance on Reanimation from max of 10% to max of 15%.
• Increased conversion chance of Return of the Fallen from max of 10% to max of 15%.
• Updated Protection of the Unity CultureShieldRegenAmount to a max of 150% at level 3. Note you will only get the full benefit if your ships are within a fully saturated region of your culture.
• Advent Repair Bays should no longer have the Recharge Shields ability.
• Recharge Shields should now have the correct HUD icon.
• Flagships can no longer be Resurrected or Reanimated.

The underlined changes are the only ones that effect flagships and Advent abilities.

Most likely.
