What gameplay feature is this bug affecting?
My King's Heritage

What's the issue? Please include any error messages you receive and as much detail as possible.
My king's heritage was clean, but it changed recently pretty spontaneously to dirty. As far as I can figure the father's registered as an older version of the king that showed as my king's father when I kinged him. If that makes sense.
