To fix the issue of not being able to edit pre-existing Sims 4 households, you can follow these steps:
1. Open the Create a Sim (CAS) menu in The Sims 4 by clicking on the icon in the lower right corner of the screen that says “Create New Household in CAS.”
2. Once you’re in CAS, click on the icon that looks like a folder, usually located on the upper right corner of the screen. This will allow you to load your gallery.
3. In the gallery, find and select the household that you want to replace. This will load the selected household into CAS.
4. Now, you have the ability to make changes to the household. You can edit their appearances, personalities, relationships, and more. To change relationships, click on the “Relationships” tab, usually located on the left side of the screen. From there, you can modify the relationships between the Sims in the household.
5. Once you have made all the desired changes, you can save the edited household by clicking on the checkmark icon, usually located on the bottom right corner of the screen. This will save the changes and allow you to use the edited household in your game.
6. To put this family in the game, exit CAS and return to the main menu. From there, select the “Manage Worlds” option. In the world management screen, choose the save file or neighborhood where you want to place the edited family.
7. Once you’re in the chosen save file or neighborhood, select an empty lot or an existing lot where you want the family to live. Then, click on the “Build/Buy” mode and choose the household icon. This will bring up the household gallery.
8. In the household gallery, find and select the edited family that you saved earlier. This will place the household onto the chosen lot, and you can now play with the edited family in your game.
By following these steps, you should be able to overcome the issue of not being able to edit pre-existing Sims 4 households. Remember to save your progress regularly to avoid losing any changes you make to the family. Enjoy customizing your Sims and playing the game with your edited household!
