The latest update for The Sims 4 brought a series of helpful game improvements, bug fixes, and issues of its own. Perhaps one of the most common and annoying issues is the alien disguise bug that leads to Sims 4 not working.

More specifically, all full aliens born in the game or created through genetics in CAS will lose their alien looks when players edit their characteristics. On the other hand, normal aliens don’t seem to be affected by this issue. Keep reading to find the solution!

What can I do if Sims 4 Alien Disguise is not working?

  1. First, you need to make sure that your alien Sim is in their disguise. Sometimes, the disguise may look alien because of the bug, even if the disguise isn’t selected.fix sims 4 alien disguise not working
  2. Go to a mirror, and select Change Sim. It is worth mentioning that the Alter Disguise and Plan Outfits option won’t work.
  3. Now, select the bottom portrait, the Alien form in CAS, not the disguise.
  4. Change the alien’s characteristics as you wish. If you try to edit the disguise again after it’s been saved, it will be overwritten by the alien form. This means that you’ll have to start all over again.
  5. Save in CAS. The Alien form that you changed should now be the Human Disguise.

The bad news is that you cannot edit this later in CAS, but you’ll have a human disguise until The Sims Studio patches this bug. You can also try repairing the game with the Origin client or reloading the save file.

We can also suggest reinstallation, but that’s the last option, and it’s not something you should do before trying all the other steps. But if it comes down to that, uninstall the app and then download the game all over again.
