Re: The text shows up as boxes

@r751mg1ujqu9 Did the problem occur when the mods folder was empty *and* you looked in the The Sims 4 folder directly for localthumbcache? Don't rely only on searching. Look in Documents > Electronic Arts > The Sims 4. 

If you've not deleted that file before but still aren't seeing it, there's a chance you've got a folder issue and aren't in the folder the game actually uses. What's the full folder path of the folder you've been changing mods in? The things above the Documents > Electronic Arts that you're looking in.
