I saw that happen in a game where I deleted the tombstones of dead sims.  (At the time I was acting on erroneous advice that it would stop lag, but little did I know that it could actually make it worse or cause corruption.)  I think the technical explanation if it isn't a living sim is that it's a "mini-sim" in the game, which is how the game renders foreign sims when they're not in your world.  If I understand it correctly, the game doesn't realize that sim is a ghost or dead, and is storing just basic information about the sim because there is a tie to sims in the world.

Ok that makes lots of sence, i got myself a storyprogression mod and when a sim dies now it goes to the nearest graveyard
