CAS not working, neither do icons

Hey, so I really need some help to what is going on with my game. I hadn't played it for quite some time, when today I decided to do yet again another mod cleanup but first had to do all of the updates. That done, I put 3 of my custom content folders hoping to clean those first. 

Here's what I observed when I opened the game: San Myshuno and University world icons were replaced with this gray llama icon, same thing with some info icons of places in the worlds. 

                                                                               A bunch of sims (from played and unplayed families) had those exclamations points and red markings as you see when you have broken custom content

At first I thought maybe it was indeed some broken cc I had in those folders and the llama thing was appearing as the icon of some traits so I thought the traits folder must be the problem. 

The thing is that I took all of the folders out, opened the game again and the issues are still there. and I cant figure out either why the sims have those broken cc markings if they dont have any cc on them. 

After that I tried changing the save files. I tried taking all of the save files out and just started the game with no cc and no previous save files. The issues are still there. Finally, I decided to clean my tray too. I opened the game all over and right off the bat as soon as they tell me to create a new sim, the sim appears all red and white with exclamation points but how is that possible? 

The weird thing though is that if I randomize the sim, sometimes a "normal" one appears, so can it be something related to the skins update? 

The llama thing in the icons needless to say, it still keeps on appearing.
