Issue with mouse and slider in CAS

Hi @cherryemi - These symptoms have been reported for users of the Reshade mod. Since you said you tried it without mods, it's possible that you didn't completely remove the mod, or maybe there are other mods or cc contributing to the problem.

We are due to have a patch sometime today, Sept 5, 2019 - so, you should wait until your game is patched to perform these steps. If you use mods or cc, you should go through these steps every time your game is updated with a patch. Patches can break mods and cc, and you will need to check with the creator for any updated versions. 

After the patch, I suggest you try to repair your game -

• Exit TS4 and Origin completely.
• Save a copy of your Saves folder to your desktop (or somewhere else safe, to use as a backup)
• Move your Mods folder to the desktop
• Delete the file localthumbcache.package Default location is C:\[YourUserName]\Documents\Electronic Arts\The Sims 4  Instructions with pictures are here: https://sims4.crinrict.com/eng/2014/09/delete-cache-files/
• Launch Origin "As Administrator" (Right-click Origin.exe, choose Compatibility tab, Check the box next to "Run this program as administrator")
• In Origin, right-click The Sims 4 icon and choose "Repair". Origin has to be online for this to complete. Let the repair run until completed, on the game and any add-ons installed
• Launch The Sims 4 and check to see if the issue is fixed. (your sims may be naked or bald, depending on the mods or cc that was installed previously)

If the issue is fixed after the repair, then you have one or more outdated mods or cc. This will take a bit of detective work; one at a time, copy your mods back to the mods folder, then open the game and verify everything is working. (remember that mods are automatically disabled after a patch, so turn them back on in the game options) If you have a lot of mods or cc, use the 50% method. Once you've identified the culprit(s), check with the creators to see if updated versions are available.

Please reply back and let us know if this worked. Happy Simming!
