I have a level 7 breeding sanctuary, I am level 51, but I don't know how to use my Red Rose Dragon, or any of the others that have been bred in the Ancient World, to breed in the normal Dragon City, ie I want to be able to breed an Abyss Dragon, which requires a Rose Dragon and Apocalypse Dragon, but I am unable to select the Rose Dragon and send it to the breeding sanctuary, why is this the case, what have I missed?
