Happy Simming!
There are few moments more frustrating for a simmer than clicking “Play” on The Sims 4 , watching the loading wheel spin, and then being slapped with a cryptic red alert box instead of the familiar plumbob loading screen.
If you are in the 5% where none of this worked, a full reinstall of The Sims 4 (back up your Saves and Tray folders first!) is your final reset. Remember to delete the The Sims 4 folder entirely from Documents after uninstalling to ensure the fresh install generates pristine configuration scripts.
In 95% of cases, one of these three steps will have you building your dream home again within ten minutes.
