Yeah, this is super annoying. This bug has been around for ages and I really wish they'd fix it. As it is, I end up frantically looking around and using cheats to make every vampire I can find leave individually, and it's such a drag. It's clearly a bug as it doesn't always happen whenever a vampire is on a public lot, and it's one of the most disruptive so I really think they should prioritize it.
These days,vampires don't even seem to break into any of my sims homes anymore! And more than once when it's happened, the vampire is WORKING at the public lot, as a bartender or something. It's so ridiculous!
