Sims 4 update addresses glitch with genetics after skin tone overhaul

There’s a patch for the patch after the Sims 4 December skin tones update.

The Sims 4 released a small patch on Monday to fix an issue with genetics that began after the recent skin tone overhaul update.

Last week, The Sims 4 added over 100 new skin tones and a customisation slider to the base game, a much-needed change to make the game more inclusive and diverse.

After the update, however, when two Sims with different skin tones had a child together, their offspring would always end up with the lighter skin tone.

This problem was present both in Create-a-Sim when the “Play With Genetics” option was used and in Live Mode.

A small update, for which the patch notes included the simple message below, was available to download on Monday.

Hello Simmers,

We have an important update for you to address the issues with Genetics, in which skin tones were not being applied appropriately. Thank you for your reports and assistance in tracking down these issues.


We’ve given the new update a quick test and can confirm that in our (with mods and CC included), the initial tests in CAS were far more diverse and representative. We have not tried it in Live Mode or with a fresh save / some of our older saves.

More tests to come over the next few days, but credit to the Sims 4 team for acknowledging the issue swiftly.
