Did you also try the recommendation above regarding the install directory? I think your other post indicated that you reinstalled the game and might have already done this, but I just want to be sure you're all set!
Also, the reason your Norn and the egg disappeared is because the game crashed. It has an autosave feature, but if it crashes and hasn't saved yet, you'll lose all progress. I recommend making manual backups of your world from time to time to avoid losing too much progress if this happens again. Hopefully you're all set, though, and the Health Kit is working for you!
