Endless loading when trying to load any household (specific save)

Same here.

99annamarie​ MISSNASHA​  Please remove your Mods folder and test again.  You don't need to save your progress.

If that doesn't help, try a different household within the same save, and also a different save for comparison's sake.  The question is whether the save is the issue or the game in general.

If at least the different save is fine, please open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see.  Try again to load your main household in your main save, and if it gets stuck loading, look for a new lastexception.  If you find one, open it and copy the text, then paste it into a reply here.  Please only provide a LE that was generated with your Mods folder removed.

This same exact thing is happening to me. I'll follow the steps listed and report back if it works. I just updated today. Before I opened the game or even updated, I updated the mods (I only have UI Cheats by weerbesu and MCCC) and the game so seems more likely that it would be an issue with the update??

I'm not sure if this would apply to your game - but I'll repost a reply I made to a similar thread:

The same thing happened with my game, I made sure my all my mods were updated - but I removed them prior to loading the game after the update. My played households would not load - but the unplayed households were fine. I did more research and found someone say if you use custom food cc, there may be a plate stuck somewhere on the lot that would prohibit the lot to load. So I put my mods back in the game - and it worked! I was able to load my households again. So if you use custom food cc - place them back in your mods folder and reload the game. Hopefully that will work. 

MISSNASHA​  Then I would like to see a lastexception, as described.

dewcorvette​  Can you load a different household within the same affected save?  Can you move your main household to a different lot and load them there?

 I 'don't have any last exception.

MISSNASHA​  Then try loading a different household in the same save.  If that works, try moving your main household to a different lot and see whether you can play them.

Same here.

dewcorvette​  Would you be willing to share an affected save with me?  I would only pass it on to EA/Maxis (if they wanted it) and/or to the other helpers who test saves (if they were interested).  I don't know whether your saves are fixable, but it would at least be interesting to look.

If you'd like to share, upload the saves to a third-party filesharing site (Google Drive, Dropbox, etc.) and either post the link here or send it to me via PM.  If you use Google Drive, make sure to choose the option that "anyone with the link" can view the upload.

And just to take a wild swing, how many lot traits are assigned to these lots?  You can check in Build mode.  A few months ago, there was a major problem with loading saves where the lots had excessive and/or inappropriate traits assigned to them.

So after the update it now took 5 minutes for me to load any of the households.
But i tried a new game and it didn't have the issue. 

It seems its because they changed the family tree and extended the family tag.
This means my multi generation save with a big family tree became an absolute mess, not to mention it forcibly removed marriages from anyone who was now considered family, causing even more mess.

So if your family had a huge tree or many generations, it might be the reason you can't load the file.
