Not sure. I thought it might have been a broken mod after the last update but so far I have removed all my mods, uninstalled and reinstalled, removed thumbcache file and repaired game etc etc etc but no, every time I try to save all I get is a pop up to say game save failed because of error code 300:ef52153:5dfb61ac. I can't seem to find anyone that's had the same problem and at this point my game is unplayable because whats the point if I can't save anything? Edit By Crinrict: Added Tag to Title.

I just had this problem, but I figured out the issue and found a workaround, at least to the point of being able to actually save my game without the error. I was having no issue saving at all until a few minutes ago; my sims are on a Residential Rental, but I had merged the families by this point and the only rental space wasn't being used, plus it was duplicated on the Owned Businesses menu, so I decided to just switch the lot back to a normal Residential lot. I tried to save shortly after this because my pause button was acting buggy (pressing Play after being paused, the play button highlighted, but game was still paused) thus I wanted to restart the game. I got that error when I tried.Since the ONLY thing I had done was change the lot type, I switched it back to Rental and can save again.I do play with mods, so I closed the game, removed mods and deleted the localthumbcache and reloaded that save; tried the same thing, switched the lot back to Residential and tried to save, got the same error again. Put it back to Rental and the game is saving fine.Hopefully this info will help; staying Residential Rental isn't ideal, but at least I can save on it lol.

Oh, that's actually super helpful. I had also merged families on a residential rental lot and it was when I was trying to change it to normal residential to renovate the space etc that I noticed the error. You're right, it's less than ideal but if it means I can actually save then so be it.

The game to save.Have you installed any customization with the game, e.g. Custom Content or Mods? Mods have been removedDid this issue appear after a specific patch or change you made to your system? Not sure.Okay, I just did a bunch of testing. I REMOVED my Mods Folder and repaired my game. For every test, I started a new game.Had a sim save on a Residential, Tiny Residential, and Haunted House Residential lot. Of course, saving just on those lot types was no issue. I changed the lots to a Residential Rental and if I DID NOT SAVE the game as the RR lot type and switched back to any of the other three lots, the game Saved with no issue.Every Time I changed to RR and saved the game, then switched back and tried to save the Error would occur.It seems that Residential Rental lot types break the lot when changed off that type after the lot has been saved as one.Just to be thorough, I had my sim travel to another lot (a Residential) and could save the game. I also had him move, which was... interesting? He purchased the lot as Residential, I changed it to Rental, right? Well, I didn't set up units and I think the game bugged and flagged him as "tenant" or something because when he moved, he only had just over 5k simoleons. That bit wasn't so weird, I still had to sell all his furniture. However, when he purchased the lot next door (I think 3.2k) the drop-down menu to Keep or Sell Furniture was grayed out. And when my sim loaded onto his new Residential home, he has 0 simoleons and just received the Rosebud Achievement. O_o I don't know what exactly to make of that one lol (see screenshot for confusion) And I could save without issue.In Conclusion: Residential Rental lot type breaks the lot and makes it impossible to save if the lot type is changed. The only work arounds are Keep the lot Residential Rental or have a Sim Leave the Lot and Save elsewhere.

Yes this is the problem I built the property on another land that was not residential rental and I was able to save thank you I appreciate your comment!

I have the same error/problem but on Console. This issue happened to me after having a rental property lot and changing it back to a normal household lot.

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

Best is to delete the ones you have, then trigger the error and check if new ones are created.

If that is the case, please upload them to a new post in this thread.

Please either create a .rar file to upload or copy/paste the content into your post.

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

I am having the same issue. Game won't save in San M. I was trying to change the apartment lot where the Band family lives. Janko I think is the name.

The problem is for me the experimental direct X 11 trial. When I removed the direct X 11 comment and the game defaulted back to Direct x 9, the issue went away. will be staying with Direct X 9.

@PrplPnk I was having the same issue. Tried your fix of putting it back to rental and now I can save. Thanks!
