Missing Mod and Save folder, etc...

@ashxmason

Did you find this folder in Documents or in Program Files?
Go to the Documents/Electronic Arts/The Sims4

Step 1. Rename The Sims4 folder to "The Sims4 old"
Step 2. Fix the game in Origin
Origin/Library - right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.
Step 3. Turn on the game - a new game folder will be created and you will have two - one old, one new
Step 4. Check if you still have this problem in the newly created game folder and you have your mods folder back.
If the problem disappeared
Step 5. Delete in the new game folder following folders:
"saves" and Tray.
Step 6. Go to "The Sims 4 old" folder and copy - your "saves " folder.
Step. 7, Paste this folder in a newly created game folder.
Step 8. Do the same with Tray folder and TrayDeleteItems file
Step 9. If you don't use mods - skip this step.
Check if there are newly updated version mods you are using.
Then copy and paste your mods and CC from old mods folder to the new one. First copy the scripts mods every time checking if the game is working properly. If you have a lot of CC try 50/50 method ( divide your CC into smaller batches for example 50 pieces in one subfolder and check these subfolders one by one)
Step. 10. If all is OK - delete The Sims4 old folder. Now you will have only one game folder working properly.

One question: are you using OneDrive?

I don't work for EA

I am using One Drive. That’s sort of what caused the issues to begin with. Once it got full my Documents Folder, a few mods, and a couple other things got a red X next to the folder icon. Also my main hard drive was pretty full so I moved everything on a bigger and emptier hard drive but it didn’t seem like everything went with because the only folders that popped up on the new drive were folders like “EP01” “GP05” etc. No save or Mod folders. BUT after you asked me if I was looking for those folders in Documents or Program Files, I clicked on my Documents folder and all the original folders I was looking for were in there, and it’s  connected to my One Drive. So am I supposed to be using my one drive? Because it’s just gonna get full again right? I just want to wipe everything and start over at this point.
