If you're talking the SimBin in CAS all you do is pick her and then she can be edited like normal.
But if she only has store content, that may not make a difference, as that's created by EA too. However, I'd still give it a try as a test.
Would you be willing to package her up and share her with me? Cause I'm curious if I experience the glitch as well. - Package her up and attach her to a reply.
If you do share her, she may not have her store content in my game, as I don't have any store content installed at the moment. But she'll be dressed in something.
