Load Error Code 800/801

Via cas

Hello Ruffian1950​, please take note that this reported issue is in the "Under Investigation" stage, this means that the QA team are currently working on investigating this issue.

It will not be included in the upcoming patch next week. Bugs that are included in an upcoming patch are bugs that have the "Upcoming Fix" status. 

I agree and EA Games should fix this problem forever.  I've seen so many solutions here and at The Sims Resource.  I don't know where to start.  They have an update coming and this should be fixed by them.

How do I save all of the families?

I am experiencing a recurring bug where pre-built lots (e.g., the gym in Oasis Springs, and other default EA lots) load as empty/vacant when traveled to, and attempting to travel triggers Error 801 ("failed to load lot"). This has now occurred across multiple separate saves, including a brand-new save created specifically to rule out save-specific corruption. I previously lost approximately 6 months of progress to this same issue on an older save and had to revert to an even older backup.

Troubleshooting Already Attempted (issue persists through all of the following):

• Cleared all cache files (cache, cachestr, onlinethumbnailcache, localthumbcache)
• Disabled all Mods and Script Mods entirely
• Ran a full game repair via the EA App
• Renamed/reset the Tray folder to force generation of a fresh, empty Tray
• Disabled iCloud Drive sync for the Documents folder (which contains the game's save data) to rule out cloud sync interference
• - Tested on a completely new save file, separate from the one that originally lost 6 months of progress

The issue persisted through every one of the above steps, including on a brand-new save with a fresh Tray and no cloud sync active. This suggests the problem is not related to mods, cache, Tray corruption, or cloud sync, but may point to a deeper issue with lot-loading or save-data integrity, possibly specific to Apple Silicon Macs.

Given that this has now affected multiple saves over several months and caused significant progress loss, I'd appreciate this being supported and escalated for investigation.

It’s whatever save you’re in that you’re getting the error. And you have to save all of your active families and re-add them all in cas to create the family links. It’s fiddly and very stressful. There are mods too but that didn’t work for me personally 

How does one find the corrupt save file.  And how do I rebuild in a new save?

Unable to open game and play with 801 error. Prompts me to restart game, but continues to have issue.

I could be wrong but I believe this is a corrupt save file. I had this before and when I entered a lot, the build would vanish… 14 generation save… had to rebuild in a new save

Below this reply is "The Sims 4 Technical Issues-Pc.  PC Players get help with their technical issues in The Sims 4 here."  So even though I was already in Technical Issues, I clicked 'here' and it brought me right back here!

Is there somebody here that knows how to fix this 801 problem.  I've posted over and over and am not getting any answers.
