Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.52.100.1020
What expansions, game packs, and stuff packs do you have installed? All EPs, all GPs except Dine Out, all SPs except Spooky, Bowling, Cook Kitchen, and Luxury Party
Steps: How can we find the bug ourselves? Have a baby with either two mermaid sims or one mermaid sim and one human sim. Same or opposite gender, either way.
What happens when the bug occurs? The baby does not have the genetics of their parents. Instead, the face is a random/townie face, and often the same one when tested with multiple sims. The attached image is the townie face I'm often getting (far left; parents on right). Tested with couples of the same and opposite gender, with both sims being mermaids, and with only one sim being a mermaid. No kid shared genetics with parents, though I confirmed that a baby from two human sims does still share genetics.
What do you expect to see? Children share the genetics of their parents.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No
