To be clear, after the Faylen event number 5, you're not supposed to be unable to find Nel in your body, correct? Even if you can't fix my save, or know what happened, I would at least like to know if I am just missing something.
For plot things, the bartender and fortune teller are good as advisers, because these characters analyze your progress in the game. It is difficult to understand exactly in absentia, since it is not known in what order you completed the quests.
