Re: Sims 4 won't allow me to edit my Sims

@sapphysketch  This is typically caused by a mod that affects the user interface, for example UI Cheats, or mods by TwistedMexi.  So try removing any of those if you use them, and delete localthumbcache.package as well.  If that works, look for updated versions of those mods, ones specifically listed as compatible with patch 1.88.

If you don't have any of those mods, or removing them doesn't help, move the entire Mods folder to the desktop and delete localthumbcache (again).  If that works, you'll need to sort through your mods; the 50/50 method can make the process much more efficient.
