Right! You have to be willing to give up as much as you're getting back, too. You need to start with all the materials that you plan to use.

If people are changing back, maybe you can find out what they're doing to change back. If a bath triggered it, maybe a bath fixes the problem, too?

Or... it could just be happening randomly. which means- you'll have to wait and see. You could wear something else in the meantime, maybe?
