What gameplay feature is this bug affecting?
Heritage

What's the issue? Please include any error messages you receive and as much detail as possible.
After retiring my former king, I checked my new one. When I clicked on his heritage, it was just him. No Parents, Grandparents, etc. However, his breeding info states the name of his mother (her heritage info is still there).
The current king's father was a Savage Stud.

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

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
I retire my king and choose the youngest available heir, who was three years old. I click on my current king and then click heritage. Clicking the mother's name on his breeding info works, and it's possible to look at the mother's heritage.
