[RL] Save Error 423:<various numbers>/Issue with Secret

I have this error if I hit save and I got this error over and over again but then when I stopped pressing save and always pressed save as I never got this error again as long as I never accidentally hit the save button

This error has been ruining my game ever since I started with the new Royalty and Legacy DLC. Everything worked for a few days and now it just won't save any progress. It says:

'failed to save error code 423:2A75DB5:F4062171'

I've tried various methods I found online including movie properties or switching to another family but it looks like the whole save game has been effected. Also, my saves are not being backed up by one drive as others suggested I try in other online forums. If I switch to another area on the map it will quickly flash this error on my screen before sending me there without saving as well. This has made the new DLC unplayable unfortunately. I have no mods installed at all, this is a fresh install of the game from after the new DLC released.

I simply can't play anymore. 😭 If I can't save my game, what's the point? This needs to be fixed ASAP. The error code I get is 423:с326091a:186f90b0

Hello,

I am experiencing major save issues in my game. I have already had many problems with saves failing after around 15 hours of play (for example, animals dying in “Cottage Living” where I could no longer save because the event gets stuck).

Currently, I am playing a game with the Heritage & Royalty pack. This save was working fine until the moment I tried to save and received the following error code: Error 423 (see attached screenshot). After about 15 hours of play, the save stops working completely.

I have tried many fixes: creating a new “The Sims 4” folder, cleaning my save folder, clearing the cache — nothing works. I have contacted EA twice for help, but either I get no response or they send generic technical solutions meant for other games, not The Sims 4.

I want to clarify that I have no mods or CC, and I make sure not to overload my game (I organize inventories, do not play with huge households, do not accumulate NPCs, and I don’t make overly large or cluttered houses).

Has anyone else experienced this issue?

Thank you for your help.

Hello,

I am experiencing the same serious save issue in The Sims 4 Heritage & Royalty pack that other players have reported.

• The game shows Error 423 when I try to save.
• I have no mods or CC installed.
• I have already tried creating a new “The Sims 4” folder, cleaning my save folder, clearing the cache, and checking Windows permissions — nothing fixes the problem.
• The bug happens after roughly 15 hours of play. The game either refuses to save or reverts to a previous save.

I have previously posted a detailed message about this issue, including my attempts to fix it. So far, the only temporary solution is to delete the latest save, which is very frustrating and causes loss of progress.

It seems this bug is affecting multiple players with the Heritage & Royalty pack. Has anyone found a permanent solution?

Thank you for your help!

Error 423 usually points to a corrupted save or something stuck in the world state. Even without mods this can happen after long sessions.

A couple things worth trying:

• Use “Save As” with a new slot instead of normal save
• Go to Manage Worlds first, then save from there
• Load an earlier backup from the saves folder (files ending in .save.ver0–4)
• Try saving from a different lot or household

If the save works for ~15 hours and then breaks again, something in the world is probably getting stuck (events, NPC states, animals, etc.), which eventually blocks the save process. Loading an earlier backup is usually the safest recovery.

Yes, I’ve already seen all these solutions, and I’ve already tried all of them. Nothing works. I can play for 10 minutes, and then error 423 appears again. I contacted EA directly; they had me do a bunch of troubleshooting steps, but it doesn’t fix the problem, which keeps happening consistently.
