One of my saves won't load.
After the update, one of my saves will not load. I can select it and then it stays on the loading page. I can play and load some of my other saves. How can I fix this and continue my game?
Forum Discussion
BluCheese05 Does the save open with no mods or cc present? Please test and let me know either way.
If it does not, please open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see. Try again to load this save and look for a new lastexception. If you find one, open it, copy its text, and paste it into a reply here.
This is happening to me. I had mods in my game when it updated. I have since deleted all mods and still having this issue, the save game won't open. Here is the last exception file:
