Did you figure out how to lock 'that' into the real world? It doesn't seem to work the same way as the blue ghosts method, and I haven't actually tried with the blue maiden's babies yet... I haven't been on in several days though, college started back up...
That seems what works for me the most consistently.To be specific, I use Jessicas clothes, I have not tried it with the other options, but when i walk by the mirror when i first load in, nothing, but if i walk in with her dress on, it works.

**Side hint for anyone who reads this, you dont need to *look* like jessica to get her door open.
