Re: Sims will not move or perform any actions

@syarias Did you try a reset of the game? 

Resetting your game is a more thorough way to troubleshoot an issue. It moves in a fresh install and allows you to overwrite certain files necessary to bring back in the ones you played and saved. ‘Cleaning house’ without moving out.

Make a backup first ( Save a copy of your 'The Sims 4' folder in a safe location. It can be found at: Documents > Electronic Arts > The Sims 4 )

Resetting your game without reinstalling:

Exit your game and Origin (EA app, etc.).
Move your ‘The Sims 4’ folder ( Documents > Electronic Arts > The Sims 4 ) to your desktop. (Save this “The Sims 4” folder for reference.)
Then start the game, and a new ‘The Sims 4’ folder will be created by the game.
Exit your game and Origin (EA app, etc.).
Re-add a copy of the ‘options.ini’, ‘screenshots’ folder, ‘saves’ folder, and ‘tray’ folder from the “The Sims 4” folder on your desktop into your new “The Sims 4” folder ( Documents > Electronic Arts > The Sims 4 ). Replace the newly generated files/ folders with the old files/folders from the desktop “The Sims 4” folder.
Now see if your game will load properly.
Start a new game save and see if the issue is still there.
