How do you assuage a Vampire Ghost's thirst?

@rosemow Argh! She still won't eat plasma packs or drink from people. And plasma fruit itself makes her sick. I'm making another Vampire Ghost so I can compare the two. I finally had to cheat her needs she was so miserable. I don't understand because she can travel like a Vamp and sleep in a coffin. Is she supposed to have the Vampire need grid? Because hers is human but she was a Master Vamp in life.

Edit: I finally decided she was irreparably borked and returned her to human form. I'm having her husband turn her and then I am killing her again. If that doesn't work, I'll make a new Sim.
