Re: The sims 4 game loading in progress, will not save or go to build mode

@AliceWheat81 Please rule out the chance that this is being caused by mods or CC:

Exit Sims 4 then drag your Mods folder to your desktop. Then delete the file called localthumbcache from Documents > Electronic Arts > The Sims 4. If you think you might accidentally forget to exit without saving after testing, copy your Saves folder to your desktop too, to back it up. Now open Sims 4 and see if you still have the problem. If you don't, you can start the process of figuring out what from your Mods folder was causing it. If you do still have the problem, we can redirect you to a different forum area.
