When new things are added to the avatar creation screen, as has happened recently, it appears that to change anything, you have to start from scratch. For instance, I love the new clothes option that you've given us, but in order to change to one of them I had to completely recreate my avatar's body (which I wanted to keep the same). I understand that this is due to the new items, and now when I edit the avatar I don't have to go through the tedium as I've already done it, but is it possible, where items are unchanged, to allow the option to retain the old elements into the new system.
I know this is really confusing, and I'm not sure whether I've made my self clear enough. Basically: when new items are added to the avatar screen, shouldn't our avatars remain as they were if the same components are still available.
