First off, I'm playing in Campaign mode, if that's relevant to the devs. From what I've heard, the Spirit Key is supposed to be unlocked at the Work Station once you open the museum at Wailon Lodge, but it's just not there. I thought maybe doing enough expeditions would unlock it, but no luck with that.
Without much else to do, I went to Passwater Cove to open a marine museum, but I can't even do any ocean expeditions there at all. Wondering if these are somehow related; like if I don't get the star in Wailon Lodge first, I can't proceed in Passwater Cove or something. Unfortunately the whole situation has pretty much brought my playthrough to a standstill. Was enjoying it a lot before this!
Problem with spiritual key not received in the supernatural museum. There is also the "Comprehension" module with the microscope icon which is greyed out and therefore I don't have access to it.
I specify here that I cheated a little on the money (with Cheats Engine) because in this kind of game, you are always a loser...
