Breeding pair suddenly "Inbreeding"?

[KaoRu]

As the title suggests. My pair of Bengals who have mated before are now suddenly inbreeding and have become siblings after the latest update??? What?

That is odd, but I've sometimes had the opposite experience. If I have two animals whom I know are siblings, but they have been in my trade center for a while, the game sometimes forgets to note that they are inbreeding if they end up in the same habitat with the contraception toggled off. They still have offspring with terrible immune systems, though.
