Possibly other newish factions affected too (saw a thread regarding Kapaku about this 2 years ago too)

Finished Faction Quest with the ship taking off and getting the Quest victory, but Epilogue achievement is not granted.

Game Version: 1.8.2 S3 64-Bit

Game Save: https://drive.google.com/file/d/1vwONJcCwdOfkjqp8PYqMYG-zCMSjlOL6/view?usp=sharing

(end turn to get victory)

Specs: irrelevant to this issue really...

Not sure if this game is still being patched either
