So I have this family of 5 that I had my witch kill that weren’t part of the household. 3 of them give grave but 2 of them did not for some reason, I look in the mausoleum, the house even find grave no where and it didn’t even show up despite in the family tree it show them being confirmed dead. Now I did figure out that I can cheat , go to homeworld option for some reason they show up there and invite them over and force kill to spawn a grave but i don’t want to break my game as I care about this file. Is there any idea what happen here

Did you check graves management at the mausoleum? that's where mine end up.

Yes I did. That was the first thing I did it didn’t show up. It had 3 of the graves I need but not the other two for some reason it like the grim reaper broke and never reap their soul

If you have NRaas Master Controller installed, there is an option Master Controller > Sim > Basic > Find Grave. This should allow you to locate the tombstone if it still exists in the world.

If you are not using NRaas StoryProgression, the game creates graves only for those inactive sims that are either in a close relationship with an active sim or marked as protected (previously active sims, as well as sims you manually moved in via Edit Town). Other sims don't get graves, that's by design.

So because my sims didn’t know the two younger teens it didn’t create a grave cause the family I’m trying to kill with my witch is her brother family. She know her brother and sister in law because they were active sims and move out after the wedding. She befriend the eldest child of them(nephew) a long time ago but I never had her befriended her own two nieces from them and because she didn’t know those two it what caused this whole mess of them not getting a grave is that right

Have you tried to use MasterController > Immediate > Occult: Remove to remove the ghost occult. Then use MasterController > Advanced > Force Kill to kill the sims again?
