Sims 4 Save Corruption? Every Household Fails to Load

georgiahirst​  This is a common error, caused by removing objects tied to milestones your sims have achieved.  There's a mod to fix it:

https://www.patreon.com/posts/mod-milestone-81237568

If this mod doesn't help, please provide a new lastexception, one with this mod in place (but no other mods or custom content).  You can copy the text and paste it into a reply here, and you don't need to wait more than a few minutes, or a few minutes more than the normal time it takes for your save to load.

You can ignore the unrecognized video card error, as it has no practical impact.

Thank you so much - the mod didn't work. is this what you mean for last exception?

georgiahirst​  Yes, that's what I meant, but the milestone issue is still right there.  Are you sure you added the mod correctly, and that your mods are still enabled?  Is this a new lastexception or a previous one, or did you not get a new one?  If you're not sure, delete all the ones you have and try again to load the save, then look for a new one.

yeah still not working, and this is with the mod installed and all mods turned on. This is the last exception, it's a long one sorry...  thank you so much for helping!!
