Vampire Hunters?

Well I have a Vampire slayer in my game but they just turn the vamp human - so as long as the vamps "behave" I leave them be - but if they go around breaking in and draining my sims much - well they get cured. If they behave themselves they can happily remain vamps.

I have no idea why some players cannot make a slayer - as I had no problem making my sim a slayer. Oddly his beloved is a Vampire and my slayer seems happy with her as one - but she's a good little vamp and happily sips her non-human packs.
