@tizercat When you have time for a full reinstall of Sims 4, please try that, except install the game to a different location than the one you're currently using. I'd suggest using Revo Uninstaller to remove the game and the EA App just to be thorough. Full instructions in case you want them:
- Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Sims 4 from the list, and click Uninstall.
- Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
- Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
- Close Revo, and restart your computer.
Uninstall the EA App with Revo as well. I don't have instructions for that at the moment, but the process should be straightforward. Restart again when you're done.
Install the EA App, then create a new folder into which you'll install Sims 4. The folder should be on the root level of the drive of your choice, for example C:\Games is fine, but not C:\Program Files\Games.
There's also the matter of the current download issues for certain Sims 4 packs. You may want to wait until this thread is officially solved:
