One more thing: wait until 18:00 and you'll get a moodlet "Vampiric Vigor". If this doesn't happen, then it's a glitch! Also check the relationships panel for another sim e.g. if Cornelia Goth is a vampire, then check Gunther Goth's relationship stats. She/he should have a red portrait. This is also the best way to verify if a baby/toddler/child is a vampire.
