Invisible Clothing

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Rarely (0% - 9%)
What is your current game version number? 1.64.84.1020
What expansions, game packs, and stuff packs do you have installed? Discover University, Get Together, Get to Work, Parenthood, Spa Day, Outdoor Retreat, Luxury Party Stuff, Holiday Celebration Pack
Steps: How can we find the bug ourselves? I have run across it only 2x. Once when a child aged up to a teen and the teen's pants were invisible and today when I logged in to my retail shop having saved the game and closed it while shop was still open and one of the Loiterer's shirt is invisible. I have no idea how to repro this.
What happens when the bug occurs? A Sim renders with not just a piece of clothing being invisible but that whole section of their body. The shirt itself is bugged, including all of the available colors of the shirt. I also tried editing another Sim to put the shirt on them to see if it was the shirt or the Sim that is bugged and the shirt turned the entire torso of the other Sim invisible. I really like this particular shirt, but it looks like from this point on in my game play the shirt is ruined.
What do you expect to see? Sims 4 clothing should be visible at all times and not make whole parts of Sims' bodies disappear.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

All I use is MCCC and only as an easy way to use cheats to get around the multitude of bugs inherent to Sims 4. I don't use ANY custom content. The shirt and pants that turned invisible are default to the game. I don't have a picture of the pants -- I didn't like them anyway so I will never be using them. But I sure do like this shirt and I'm going to have to go back to an earlier save in order to get it back.

Edit:: 

Oh my word I keep going back and back to earlier and earlier saves and this Sim's shirt is still invisible.

It is a Sim I have not played in a long time but want to play again. Who knows how long her shirt has been invisible. I have just lost possibly weeks of game play to this bug if I want this shirt back. I will try to find all the way back to the last time I played this Sim just for science, but there is absolutely no way I am going to redo all the hours of work I put into the game to regain my progress *with* the shirt intact.

If I hadn't already experienced such a plethora of bugs in Sims 2, Sims 3, and Sims 4, I might not be so worn down by them. As it stands, hitting yet another tragic bug like this has made Sims 4 unplayable for me until there is a fix. Again, I have never used CC or mods. This game breaks so bad on me I am scared CC will break it worse. I only finally gave in and got MCCC a month or so ago upon someone's recommendation because it was the *only* way I was going to be able to bypass an annoying relationship status bug. I love Sims, y'all. There is a reason I keep coming back. But man. I am just exhausted from the bugs. I am really going to miss this game. So much of it is so well done
