What gameplay feature is this bug affecting?
Personal

What's the issue? Please include any error messages you receive and as much detail as possible.
My deceased lion Pasha is displaying the same name in the heritage page as my current stud. Makes it look like my lions are inbred when they are not.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
Example:
https://www.lioden.com/heritage.php?type=1&id=794156465348

It is displaying on all lion heritages that are related to Pasha though.

Any screenshots you can provide us with?
