Since they don't answered, i tried to figured out the problem.
I like to play my game with longer time of life and the option "Auto Age (Unplayed Sims)" disable. So again, i started a new game, and the atack happen, i think 3 days after (game time).
I don't know if it's suppose to be like that or it's a bug. So if you have the same problem as me, and your vampire it's not attacking, try to activate Auto Age (Unplayed Sims). 🤔
Not sure how long this has been a thing, but I do have this issue as well. Vampires will show up and then just stand by the front door like any other visitor. Haven't noticed if they knock, but they don't come in and they never bite. I can invite them in like any other guest and they'll hang for a bit and then leave, but they never snack on any of my sims or really act at all like vampires.
All but one of the vampires that stop by regularly have the ability to break in (I checked) and several of them have the ability to turn sims, though NPC vampires never autonomously do that.
Caleb just broke in, mesmerized my Sim but then didn't bite. Strange ...
