Missing Objects Warning after travelling from University

Hello! If anyone could help with this I'd be really appreciative!

I recently got the University Life expansion. After my Sim had finished their semester they tried to return home and I was met with the Missing Objects Warning: Some objects could not be loaded and were replaced. The UI is completely blank, no sims, no money etc. The house my sim and her family were in is still there with the extension I built, however her family is not there or in the UI. I've also tried her dropping out of university instead of travelling home when the semester ends however the same thing happens.

If I go to edit town and then back out of it, it takes me to the game setup page as if I have opened a new file to make a new save with new family etc. My family is in my library however how they started where the sim I had at university is a child

I have tried the following steps found on another forum post:

Empty out your sims' inventories as much as is reasonable. Having a few items is fine, but not much more.
Save the game immediately before you want your sims to travel.
Exit to the Main Menu and lower all the graphics settings to the minimum. Turn off the in-game shopping experience and the interactive loading screens as well, then quit to desktop.
Delete the five cache files in your user folder (listed above) again.
Take your computer completely offline. You can sign in and put Origin in offline mode before disconnecting your computer and launching the game. Disable the Origin in-game overlay as well.
Load the game, and once the clock has run for a few sim-minutes, send your sims traveling right away.
Once they arrive in their destination, use "save as" to rename the save, then quit. If you want, you can first exit to the Main Menu and raise the graphics settings again, but be sure to quit to desktop before reloading the save.

However this has not worked, still getting the missing items warning.

I have also tried creating a clean The Sims 3 folder in the Electronic Arts folder and copying my save into the new folder. Hasn't worked.

Also tried resetSim * and resetSim mysimsname, hasn't worked.

I did have the following NRaas Mods however have tried removing them after the first couple times of this bug. Even with mods removed it still happens:
