Sims lips folding into each other

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur?Every time for the past few days

What is your current game version number?

version 1.95.207.1030
What expansions, game packs, and stuff packs do you have installed? Seasons, strangerville and a lot of cc
What happens when the bug occurs? I had just downloaded a lot of new cc that day- and suddenly sims were appearing without body parts, or with their faces glitched out. I thought it was because of the new cc, so I redowoaded some of it, and it seemed the problem had completely gone away. Then I went into cas and was moving a sims lips higher on their face, and the lips kind of twisted into each other. I uninstalled all my lip sliders- but every time I’ve opened the game since the same thing has happened. 
What do you expect to see? Sims with faces. Lips that down twist into themselves.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes, a lot. But I hadn’t had any problems at all, until four days ago. I downloaded a lot of new cc then and ever since there has been a lot of glitches. But before then, I already had over two thousand cc files downloaded, without any issue. I added a very small amount in comparison, out of which only a few were sliders and sim based. The rest were furniture. I reiterate that before then there were no problems.
Did this issue appear after a specific patch or change you made to your system? Yes ^
Please describe the patch or change you made. I added cc.
