The ending of Ghost in a Gem is busted. Bringing the ingredients to Hastophos results in him telling you that you made the right choice, and throws a journal entry saying he has already released Missa's soul. Asking him about her again, he condemns you as if you chose another quest route, but proceeds through the final sequence anyway, and takes your ingredients. Even after that, he still condemns you as if you chose another fate for the gem.
