Re: alien abductions no longer produce alien babies

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? 1.99.264.1030
What expansions, game packs, and stuff packs do you have installed? I have all the packs installed.
Steps: How can we find the bug ourselves? Looking at a abduction and pregnancy through gameplay or cheats and start an alien pregnancy with MCC.
What happens when the bug occurs? All my males sims get normally abducted and gives birth to human babies, but with MCC I'm able to start an alien pregnancy and have an alien baby. With an normal abduction looking with MCC the partner is always set to "none" meanwhile with the MCC pregnancy cheat, the partner is "senior pollination technician #3 and have a baby alien. I tried repairing my game and only use MCC and UI Cheat.
What do you expect to see? I have to use MCC for my sim to be pregnant and gives birth to an alien instead of gameplay or cheats.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

I think it might be a bug related to the partner and that's why as a human sim when there's no other partner showed on MCC the baby came out human.
