[V] Vampire Break Ins Do Not Happen In Worlds After Vampires

Oh, this is actually true. I remember this as a thing, but it doesn't happen to me at all now

I've had it happen to me while living in Nordhaven a couple months ago, but I can't confirm it works on vanilla, since play with mods.

What is a bad, but intentional, feature is that now vampires only break in once per save, ever, so this might be the reason it feels like vampires don't break in on newer worlds?

I actually have it happen in New saves in the worlds you report it does not happen. It is in brand new saves and happened because I forgot to set the front door to disallow vampires.

I don't think it's a world issue. I think it happens in the newer save and at some points stops, like some calls

In my game, the vampires do show up, but they leave right after spawning. They don't even make it past the front door, they just leave the lot with the "pillow thought bubble" or w/e thought bubble that pops up when sims leave the lot.

Please fix this. If we have the Vampire pack, we want our Sims to interact with Vampires... 

There is a mod by Kuttoe that fixes this. It's called "Vampires Everywhere." It adds a 1% chance of invasion every night with a higher chance during full moon, allows invasions to happen in Tiny Homes and Haunted Houses (for some reason its disabled) and improves their spawn point logic.
