Whenever an OccultVampire and a nonOccult Sim have a child, there is a chance they might be a Dhampyr if they aren’t born a Vampire. Like Vampires, they’ll have to wait til they’re Teens to fully manifest, mostly because their half-human nature makes them develop a bit more slowly and also because the animations would look absolutely cursed.
Sims will no longer autonomously choose to be rude towards cats and dogs just because they don't have to cat/dog lover traits. Only mean Sims will remain rude towards pets they don't know.
