In addition to locking down worlds like Moonwood Mill, Forgotten Hollow and Glimmerbrook, I would like to be able to designate increased occult activity for individual lots, the way Vampires did with the Vampire Nexus and Vampire Lair lot traits. Additional lot traits could help with all occults, and shouldn’t be that hard to implement.
Ghosts A “Graveyard” trait would be available on a lot for ghosts whose urns/tombstones are placed there. During the day families could come and pay respects/ mourn but ghosts would haunt at night. There is a mod that does something like this.
Aliens. An “Alien Base” trait would allow aliens to interact autonomously as aliens and increase chances of abductions for regular sims..
Spellcasters An “Enchanting” trait would allow Spellcasters to practice autonomous magic in their residence or on other lots.
I agree that ghosts should not have human bodily needs, and should have specific needs of their own.
