I did some testing, and it seemed to happen when the sim died on the same lot as me.

I've had this happen with sims who I created as ghosts in CAS, so not just dying on the same lot. In this instance it was sims who didn't die of old age. But who knows if that's just a correlation rather than a cause of the bug.
I created my sim's family as ghosts in CAS. The 2x ghost sims who didn't die from old age (death by pufferfish & overheating) showed as alive in the family tree.
