Vlad leaving without a sip?

I was horrified that no vampire ever does anything in my games, til I got mods, and even then, I almost never get a nightly visit, and when I do, they never feed. Never once. I did everything trying to get to see that. All they do is visit, play video games or sit reading books, then leave around 4 in the morning, whether my sim is awake or asleep. But the Great Nerfing of the illustrious Vampure Pack is Dins 4 history. They basically filed off the vamps' teeth and made them a bunch of costumed goth wannabes, because enough people wanted it only for cas items and build items but hated actual vampires and complained, enough that the vampire pack was nearly neutralized. The only solution is mods out the wazoo.
