What's the issue? Please include any error messages you receive and as much detail as possible.
I was preparing a lion to be put up for trade and noticed it was being shown as being far more Inbred Than it actually is, instead of one instance of inbreeding it showed it having seven. I have seen this happen before on other lions but at the time figured I had miscounted or my dyslexia was acting up, but a friend has confirmed I am seeing a bug.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
