So I finally finished the big fight at the Relic Trimestigus (or whatever) and repaired the stargazer. I see an Icon for Gipetto at the hotel but he isn't there and Sophia is also nowhere to be found. Antonia is in a now-opened Gipetto's lab but no sign of Sopia or Gipetto anywhere

I tried forcing a cloud save conflict and returned to just before the battle. Fought and won again but no Gipetto or cutscene or Sophia when I get back to hotel.

Is this a known bug or am I missing something?
