This is my second playthrough, so I know how it's supposed to go, but I'm stuck unable to unlock the 4th elemental portal in the homestead. Fire, Water & Earth are active, and Air is still inactive.
Zixzax is standing by the elemental statue, but I can't engage in dialog with him (He just says to go to the next chamber, or enter the next portal). The elemental statue itself is not interactable either.
This happened when I grabbed the 2 bloodstones in the Silverglen Immaculate temple basement. I used both to turn them into inert stones then picked up the inert stones and teleported to the homestead where I haven't been able to get anything else in the homestead to unlock. I have found at least one more inert stone since (the one in Maradino's Secret Lair) and still no change.
Anyone have any ideas?
