http://simsvip.com/2014/09/09/guide-how-to-resurrect-a-sim-in-the-sims-4/ I read the thread above and followed the instructions. My Level 10 Writer / Best Selling Author wrote the Book of Life and used “Capture Epic Saga…” of household member Cash Hairston (his brother-in-law) when Cash was an Elder. Cash died of old age. His wife Carpenter (still an adult) was so sad I decided to bring him back. Carpenter used the book to 'Summon' Cash and he appeared but as a ghost. Per the guide information "The Sim will return to life as if they never left" but this did not happen. Key factors: The book was written before the patch to add ghosts. Cash died after the patch. Both the author of the book (Garrett) and Cash's wife (Carpenter) tried the Summon command. Both Garrett and Carpenter read the Epic Saga. Cash did appear when summoned and was added to household per the request to join household. Cash stayed a ghost until I finally had him Return to Netherworld. (Not a reversible action.) I also noticed that before the patch the four urns on the lot had the names of the deceased family members. After the patch all but one read "R.I.P. _____" and the option to mourn was no longer there.
