No Grim/Urn when switching to household with dying Sim

• Are you using mods/cc in your game ? Please remove them and test without them if you do.

No mods. No cc.  I have it turned off in game options. 

• To be sure, you got a message that they were already supposed to be dead and yet they still were alive when you switched there or was the message that they were about to die ? Or did you load an earlier save ?

I did not load an earlier save.  Opened the game as usual.  Playing in 'Xavier household' for awhile. 
Text box pops up that Eve, who lives in another household, is dead and it gave me options to select what happens to her inventory.  I click Add to household inventory.  
I keep playing Xavier household to finish what I was doing there before I switch over to Eve household.  Then a second text box pops up saying that Eve's husband is dead and the same options about inventory. I click Add to household inventory.
Then, I switch to Eve household.
Eve on the floor, dying.  Grim comes inside and does his thing. Family cries. Eve's tombstone is there. 
Eve's husband was not in the house.  He arrives at the house after she dies.
Husband goes to do yoga autonomously.  I'm watching him. Waiting for him to die because of the text box.  AND HE DISAPPEARS.. poof.  No tombstone or urn left. Grim does not show up. Husband is gone from the household.  

I check the daughter's relationships and her father is a ghost.
I look for his tombstone in the house.  I look at the household's inventories.  No tombstone.

• When you saved and reloaded where they still gone ?

Yes.  I just opened the 'Eve household' to double check.  Both Eve and Husband gone and ghosted.
