My moonstalker lupora has three visible traits, as I used an exceptional blood vial on it, but it should also have three hidden traits from the vampire dust I used. It is a hatchling, and I used the genetic test kit on it, but its information shows no hidden traits. What's going on?

Your Lupora actually does have hidden traits - I think you may be confused to what the Vampire Dust does; it adds a Hidden Trait to any visible traits, rather than giving your Pet carried traits. I took a look at your Moon Stalker Lupora and she appears to be carrying the Runic Swirl Gene behind her Shadow Markings (Shows as AI), the Faded Leopard Gene behind her Doberman Markings (Shows as BF), and the Mystic Ribbon Mutation behind her Spiked Collar (Shows as AC). You can tell when you manage to look her up in the Advanced Search options. Her Genes have two different letters on them rather than just AA or DD.

Ah, I see now. Thanks.
