Re: CC not showing up in game
@FormalFudge Try deleting localthumbcache.package, in your Sims 4 user folder.
If that doesn't help, please move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. Launch the game to create a clean folder, reenable mods and custom content, and quit. (Your saves and other content will be intact in the folder you've moved but temporarily not read by the game.) Then move one mod that you know is updated for yesterday's patch—download a new version if necessary—to the new Sims 4 folder, and see whether it appears in-game. Let me know either way.
