I was informed by YomiZex that the original fox from which mine had come had been retired, so I went first to check what was happening. Since the account carrying that item was retired, regardless of the fact it claims on the page that it is still derivable, once you try to derive from it, the creator wont let you. I even checked the link to the map files, and it too is broken.

In light of this, I am making one of my foxes, the most basic of them derivable, I have also dropped the profit off this one, and I am providing the original maps here,so that the creativity can continue.

Muses Bless You All!

Thank you YomiZex for bringing this to my attention!
