Vampire Hunters/Those I Turned Are Immortal

By default, my game sets Vampire Hunters and those you turn into Vampires according to your skills and abilities. This means that they spawn or change into a reflection of your stats.

If you have used the console to enter "god mode" (tgm) or you have grossly inflated your own stats to effectively be unkillable, then Vampire Hunters and those you turn into Vampires may also be "immortal".
