I completed the Antiquarium Site twice and it still says that it's running, not completed on the map. I have already crafted Antiquarium cards, so I think that it's just an issue of the game fully recognizing that I've completed that area.
Hi there,
Thank you for bringing this to our attention.
To confirm, is this the message you receive if you hover your cursor over the map icon for the Antiquarian Hub? Or is the message appearing elsewhere, such as in your Guidebook?
