Thanks, Ratchie. She's eaten ambrosia. I did a big thing where she had to eat it in a fancy setting in front of the grave because I'm warped like that! I figured since she needed 10 cooking she might as well do the food, too.
So word of advice to anyone else, submit food a the last thing if you plan on doing so and ship off your ghosts once you have food. I'm not sure what else they could mess with. Do ghosts pick up items and carry them around?
