I have noooo idea. XDD Apparently certain items do that or something, idek. For me, it's the jacket...thing. Uh. One of the new things...Striking Theif? That.
...I think I can confuse it into thinking the item is on when it's not, though, if I'm careful. I've been dressing Sherlock up in dresses and laughing my a** off for like an hour now. XD
