My game keeps getting stuck on the loading screen

The same thing is happening to me. I was able to click on a random household and it loaded in but I couldn’t let that sim travel to my current household. It got stuck on the loading screen again. I tried to build to bulldoze the lot to replace it but I’m stuck on the loading screen again. It was working perfectly fine yesterday. 

Hi jzicaro​ keyera_byers16​ 

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Posting the info is meant for troubleshooting. 

Thank you! This is the new Last Exception script:
