Re: Sims 4 cannot click on tents at all!
Testing on a vanilla (no mods/cc) folder is the best way to investigate causes of issues.
Along with removing (not disabling) mods / cc the localthumbcache.package needs to be deleted.
Here is what I recommend.
Go to Documents\Electronic Arts\The Sims 4
Rename The Sims 4 to The Sims 4.old to preserve your saves, tray, screenshots and mods folders/files.
Run Repair from Origin as described in the troubleshooting guide.
Start the game without adding anything back as a test.
The game will automatically create fresh versions of all the folders/files.
If the game works correctly you will need to test your mods /custom content (CC) to see which they are causing the problem.
Using the 50/50 method is suggested to speed up the process of finding the mod causing the issue.
