I stumbled upon another issue with the avatar creator: It often only loads part of the items, both upon initial load and on clicking the "restore" button.
It generally always loads items that I didn't touch between the last two saves, and doesn't load most of the items that I did change.
How to reproduce:
I used these two sets of items, but it probably works with any.
* Save avatar with black hair and blue eyes
* Go to the edit avatar screen. If both eyes and hair are displaying correctly, do the following:
** change the hair to brown and then right back to black
** change the eyes to brown
** save
* Go to the edit avatar screen again. It will fail to load the hair or eyes.
I sometimes do get different results (missing hair, missing eyes, nothing missing), depending on the order in which I do these steps and the row the item is in (or maybe it depends on the actual item, I'm not sure).
