Oh, shoot... I assume you're sending them to rehab from the dungeon? It seems I forgot to do a cleaning check on that part... all fixed for next update, thanks!
As for the Ophelia thing... if you Shattered Ophelia before the rehab update then the game doesn't know that you Shattered her, and so allows you to rehab her. Any girl Shattered after the rehab update won't be rehab-able :)
