Ummm... I have a problem. I really hate when the vampires show up on community lots on Downtown. I have many businesses there, and the vampires started to go on some kind of biting spree which included biting everyone on lot, including Mrs. Crumplebottom ... and guess what, my game got messed up.

So what I am looking for is a mod that keeps vampires away from community lots. Does anyone know a good and safe one? Then please help me!

Sorry for my bad English.

You can use the visitor controller and ban them from showing up:

Thank you!! I will try this.

Pescado's creaturefix prevents vampires from biting NPCs, including Mrs. C.

And you can get treeag's Sim Transformer to turn everyone back to normal
Or you can go the non-cheaty way and summon the Gypsy Matchmaker.
