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.
My king's cubs are showing as deceased on their page. When you click his link, it shows 'This lion does not exist!'
If you check the heritage, you can clearly see that he is alive by clicking on his link.
The lineage is the same as my current king, but for some reason marks him as dead?

If you click on his name on the cub's page, it'll show "this lion does not exist!" and bring you to a dynasty page.
However, the lineage remains tied to my current king, who is not dead.

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:
Cubs were born this morning. I noticed it said 'deceased' when it surely shouldn't.

I heritage replaced him yesterday, but did not breed him once prior to making him a cracked. Mass breeding all took place after repping, as can be proven by the Cracked cubs born in the mass breeding today.

Just click on one of his cubs' pages and you'll see "Alanis' Interlude (Deceased)"
and clicking on his name under 'father' on the page will lead to the does not exist page.

If you open full heritage, clicking on his name will lead properly to my king.
