I've made 2 requested mods by:
André -> mod to make Vampires ignite if exposured on sun for too long:
VampiresMood OnFire version
NOTE: No one will extinguish fire on your Vampire, he/she is meant to burn to ash.
Burning down takes 1 sim hour.
Benjamin Enns -> Vampires will always bite in the neck, but it will not always be succesful:
DrinkfromeveryoneVampires D -> D is for Default
