Hi @NereidaVB - When you send a ghost to the Netherworld, they're completely removed from the game, so you can't call the ghost over to divorce them any more. That being said, it seems like if the sim is gone, you shouldn't have it in your relationships at all anymore.
I suggest you try to repair your game -
- Exit TS4 and Origin completely.
- Delete the file localthumbcache.package Default location is C:\[YourUserName]\Documents\Electronic Arts\The Sims 4
- Launch Origin "As Administrator" (Right-click Origin.exe, choose Compatibility tab, Check the box next to "Run this program as administrator")
- In Origin, right-click The Sims 4 icon and choose "Repair". Origin has to be online for this to complete. Let the repair run until completed, on the game and any addons installed
- Launch The Sims 4 and check to see if the issue is fixed.
The other thing you might try is to recover a previous save, from before you released the ghost to the netherworld. Unfortunately, you would lose any progress you've made since then, but you could divorce your ghost before you send them to the netherworld. https://sims4.crinrict.com/eng/2014/09/save-games/#wiederherstellen
