I'm trying to create a large cavern but I'm having difficulty setting up new exterior cells. I've created the worldspace, all the settings are ready for it, location, encounter zone, etc. But while I've got some lovely wilderness sections I can't create new cells for the cavern itself. I've tried duplicating the wilderness sections but it doesn't react. Is there some different way of doing it for exterior cells I'm unaware of?
Thanks
Cya
