Vampires don't break in anymore?

I've only had Vlad with his usual "welcome to the hood" thing. I lock the doors, so he can't get in, but he still managed to mesmerize my sim through the wall.....? The *bleep*...?

I'm usually playing in Sulani, Mua Pel'am, with Private Dwelling lot trait (especially if my sims have started to gain fame). The vamps don't seem to manage to find their way to my houses there.
