Ok, so I have this weird problem within my game where I'll be playing and everything seems normal and then randomly the clothes start disappearing off of my sims in game randomly. For example, I was at a bar and my sims were talking to each other, next thing you know the clothes disappeared off of everyone on the lot except for my sim. Shirts, Pants, Shoes, and even hair and I don't know why. Has anyone else been having this problem or know what to do?

Yes I have Mods. None of this weird stuff really started happening until the Pets Patch. Ever since little inconveniences keep popping up.

Try to remove them and see if the game works better.
For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.
If that works but you want to keep your mods, you can try some different things to sort out the ones not working. In your case, I would focus on number 2 and 3. Number 2 fixes mods like scripts, traits and such, while nr 3 focuses on cc like CAS-stuff and buy-objects.
Good Luck!
