All Occult Sims VANISHED

After the most recent game update, all of my vampires, werewolves, aliens, etc. have disappeared (INCLUDING TOWNIES!). I do play with mods, so I went through the usual process of going through those first, but this truly does not seem to be a mod-related issue. I attempted to make a new save in my game, but this also did not fix the issue. I can remake my lost occult Sims, sure, but the townies, too? 

Sure would appreciate it if this could get fixed. Vlad, Greg, all gone. Not cool. 😭
