My occult sims won’t drop a urn or tombstone when they die.

I have killed off 4 occult sims and not one has dropped an urn or a tombstone. I have no mods that could affect this, the only mod I have is the MCCC and it’s what I used to kill them off. The only occult sim that gave me a tombstone was a mermaid. The werewolves, vampires and spellcasters didn’t drop a tombstone they just turned into ghosts. I even took away their immortal traits if they had one. And idk how to get their tombstones or why they didn’t even give me their tombstones.i’ve had this issue way before the love struck update and I’ve been trying to figure this out for the longest
