The rules for the ANY% say that "Time ends when the spiritfarer logo appears at the end after the final constellation". With the most recent version of the game you do not have to complete all constellations in order to get to the Spiritfarer logo.

My question is, in light of the updated version of the game, will this rule be adjusted?

If I were to do a run should I be trying to complete the constellations or getting to the Spiritfarer logo?

Any% never did require you to complete all spirit story lines. Just completing the "Stella's last voyage" questline should be enough.

Good to know!
