Game can’t advance

I just talked to malde in Narra Town so I went to the darkening cultist base but there was nothing there. I could get into the base but nothing happened. I looked up a guide and it said Persephone was in the sacrifice room. Is there something I missed or did I somehow break the game?

This bug has happened to some others and unfortunately I have no idea if it’s been resolved for them either. Some sort of bug must’ve occurred.
