The “Edit in CAS” option shows up, which would edit your selected sim. Whenever you meet this bug, always type testing cheats true and then press shift and click the sim you want to edit. To use the editing cheat, you need CAS full edit mode.
This will pop up the command console, which would help the players to input the cheat codes.
Now, to enable the commands for the cheats, you need to hold the CTRL and SHIFT keys down and press C. In spite of whatever means of gaming you’re using, PCs, Xbox One, or PS4, you could enable cheats for editing your Sims. This will provide you with new cheat codes that allow you to edit the objects or your Sims in the game.
