Hello everyone. 

Weird issue: I can not explore the Netherworld, which I could previously do. 

I have achieved two stars in both Memento Mile and Passwater Cove. No stars yet for Wailon Lodge, but I made some progression already before this issue. 

I also already made the Spirit Key but I can not use it since I can't travel to the Netherworld. 

And I can't restart this museum either. On the museum map, the only option I'm getting for all museums is "continue". 

I didn't make curator class III yet, one achievement to go (receive bronze in pop up exhibition).

So is the game just bugged and do I have to start everything all over?
