CAS IS NOT WORKNG

Hi @TheImfe just confirming that your game works as intended when vanilla (ie: no mods or cc) and 'repair game', along with deleting the localthumbcache.package file from your sims 4 folder?

Mods and CC require maintenance to keep them in your game, if the modder has not updated it after a game patch/update it may be broken (you can check via the mod tracker for reported broken, etc mods). As there is undoubtably a broken mod / cc causing your issue.

1. The process of culling & removing it, to find the broken mod is the only option though, you'll find it won't be 'all of them' but a few or even just 'one'.. 
2. After every patch or game update, this is a necessary process, to add your mods back to your game, folder by folder and starting it each time to test to see if it's ok to play. (nb: you should keep them separated for ease of checking, btw)

Also,  if you are new to using cc/mods please check my post here on maintaining your game.  as there is many tips including the 50/50 method and tools to help you fix your game and how to find the broken mod. 

Hope this helps. 

Sasha
