Hello. Thanks for the tip. I only adjusted the syntax in the programming after the patch, but did not change or check any semantic structure. If it is as you describe, then something seems to have been changed in the game that changed the inheritance of traits. I have to look much deeper.
All the mods are from baniduhaine:
Alien Bloodlines
Vampiric Bloodlines
Werewolf Bloodlines
Dormant (Alien, Mermaid, Speelcaster, Vampire)
Dhampyrs Extended
Those are the mods I use the trait injector for. The updated version you released when in the Mods folder causes babies at the time of labor in the hospital to not show up in the crib next to the machine. And when home birth the babies appear but when you age them into infants they´re human (when the parents are occults) and unrelated to the sims that are their parents. In the Family Tree they show up alone.
