A new update has been released for The Sims 4 to fix your demonic babies, so wave goodbye to them! Origin should automatically download and install this patch for you.
Bug Fixes / Issues:
It has been brought to our attention that some of our cute and adorable babies have had difficulty expressing themselves without… well… distorting. There was an issue with some integrated chipsets causing the poor little ones to appear in their own “unique” way. We have corrected the problem and pulled everyone back together. Thank you for helping us identify, and track down this issue.
