CK II - Children born to married couples marked as bastards

[tilly]

One line summary of your issue
Children born to married couples marked as bastards

Game Version
3.0 (PTXU)

What expansions do you have installed?
All of the above

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
Periodically the first child born to a married couple who are also lovers will be marked as a bastard. Sometimes the mother is also marked as an adulteress (not always though). Child does not have to be the first child of both parents, just the first child in the union. Bug does not appear to affect twins. Appears to more often affect sons than daughters, and younger couples more often than older ones. At least one parent must be landed. Both parents may have to be AI controlled.

Steps to reproduce the issue.
Marry two characters, console them into being lovers, console the wife pregnant by the husband with the pollinate command, and then force her to give birth immediately. Allow some time to pass as the game will initially register the child as legitimate.

(Bug will also occur without console shenanigans, but it isn't consistent and may take a couple tries to reproduce, so this is much faster)

Same issue, Byzantine Emperor, 769 start, all expansions. My second son, Christophorous, married Charlemagne's sister. Their first and only child, a daughter, is a bastard.

Just want to add I have seen this as well.

Yes, and if you are the husband and your wife is also your lover, you'll get the "doubts beset me" event right after getting the "my lover told me she's pregnant!" event, so you end up being jealous of yourself.
