Early Access version 65

• Supernova missions: “Shoot the Core” is now a potential boss (@OneWingLunarian @xXmlgDiegoXx @GoldenBoss128 @IceIris Idea)
• Comet Chase missions: “Mysterious Ship” is now a potential boss
• Feather Fields missions: “Twice Infinity” is now a potential boss

iA, make sure to change the music during original potential bosses instead of victory theme?

Also Assassin Chicks should be removed from “The Fortress” wave.
