[PC/MAC] Game couldn't save due to error 13

The date is 10.15.25 and I have noticed a bug. I have spent hours building a small business "bed and breakfast". I have saved the game multiple times and I had no issues saving UNTIL I went to open the small business and now I'm getting an error code 13. I built the lot from scratch and I don't have any mods installed on my computer for sims. Its super frustrating not being able to play the game the way its intended to be played. I wish EA would do better about the quality of their packs and content rather than the quantity...ugh. Any ways I can fix this on my end?? Or will I have to wait months for a fix?

 I'm also playing on pc an have checked the integrity of my game files just in case that was the issue.

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. 

Hello all,

If any of you are still encountering this on the latest game version (without mods), would you be willing to share your save file(s)?

If so, please send me a private message with a link to the file. Instructions can be found here: https://forums.ea.com/idea/the-sims-4-bug-reports-en/information-how-to-send-user-files-to-the-sims-4-team/5048472

Thanks!

I have gotten Error Code 13 twice now, on the same Save. After the first time, I repaired the game, did a "Save As", and it worked for several days of irl play, until today. I play vanilla on a Windows 11 laptop. I own all EP's except EbN, AA, and all other dlc except for about 5 kits. I was playing on a residential lot with a small business. It did throw a last exception notice, and I am willing to send my save. I'll have to look into how to do that. Am very much not tech savvy, so I'll consult my son for help with this. I just ran another repair, and will see if this fixes the save for now. Have also been having issues with the in-game notification wall in this save, with an old message remaining in the queue, covering the newest ones. It refuses to be deleted. If I try to delete it, it deletes the new message hiding underneath. It comes and goes. I'll search to see if this is related to the error 13 bug, or a separate issue.
