Same reason the other girls were removed. They requested it and we have to respect their right to do so. Totem have to comply with the performer's request. If you look at the Camilla cards missing threads for example it is explained in full detail.

If you have the card downloaded now would be an excellent time to make a backup copy of the model and data files for those cards on DVD for example. That way if there is a problem with your PC and you lose the cards from the HDD you still have them to put back at a later date.

Edit - With regards downloads of removed cards no longer being available, Totem very kindly upon request will put a credit back on your account if you cannot recover a card because of this removal.
