Re: Help! My entire game of Sims 4 is gone after update

can you tell me what deleting that would do? I don't want to delete anything without knowing what it does

It clears the cache. The game will create a new localthumbcache.package file.

I really know nothing about computers, sorry that I sound dumb, but I don't know what a localthumbcache.package  is or what it does. What does it store? And will deleting it bring back my game?

@TallieAtap0401

localthumbcache.package is a cache file that can get big fast. It gets recreated after it's been deleted. It's a good idea to delete this file when having issues with the game and/or adding/removing custom content or mods.

It may not bring back your game, but it helps with troubleshooting the issue.
