Coward's Submission Bug (I think)

Yep, its a bug.

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

Yeah I thought that was in the changelog...what gives?

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.

Ugh...well this is most unfortunate...probably never caught before sisnce Coward's Submission didn't work...

Most likely.
