I haven't played around with the pregnancy stuff too much yet, but there seems to be 2 different birth scenes where the child's age gets set to 18. I'm not entirely sure how the game determines which one is called, but
Ravenger6660 might know:
Code:
vin_Pregnancy\Scenes\NPC_gives_birth.lpscene
vin_Pregnancy\Scenes\NPC_gives_birth_neutral.lpscene
I guess maybe NPC_gives_birth is called if the player was the impregnator, and NPC_gives_birth_neutral gets called if the pregnancy was between 2 NPCs? But it seems like the bottom of NPC_gives_birth also has a branch for no involvement by the player, so I dunno.
