After updating The Sims 4 from version 1.117 to 1.118, one specific save became completely unplayable.

Before the update (1.117):
– The save worked normally
– All households loaded without issues

After the update to 1.118+:
– The main menu loads correctly
– The affected save appears in the Load Game menu
– The world loads successfully in Manage Worlds
– BUT the game crashes to desktop when trying to load ANY household
  (including newly created households on empty lots)

Important details:
– This happens with NO mods and NO CC
– localthumbcache.package deleted
– Clean user folder tested
– DX11 and DX9 both tested (no difference)
– Repair via EA App done
– NVIDIA shader cache cleared
– All backup versions of the same save (.ver0, .ver1, etc.) crash in the same way
– Other saves and new games work normally

System:
– Windows 11
– NVIDIA RTX 4070 Super
– EA App
– Game worked correctly on version 1.117

Conclusion:
This looks like a save compatibility / serialization issue introduced in patch 1.118, where existing saves crash when initializing households.

The save cannot be rolled back because EA App does not support version downgrades.

Please investigate save compatibility regression between 1.117 and 1.118.

It's always helpful to have saves to test that are known to be broken in a specific way.

Yes, of course.

Here is the save file that worked in version 1.117 and started crashing after updating to 1.118.

Symptoms:
– The world loads correctly
– The game crashes when loading any household
– Happens with no mods or CC
– Other saves work fine

Thank you for looking into this.

Hi Rizuha​ 

tested your save and the game crashed with a lastException. Don't know much about it but I merged your post with existing bug report.

Attaching the Exception.

Did you try to run the game with all the mods you had before (updated if necessary) ?

Hi crinrict​ 

Yes, I tested the save both with mods and without mods.

The issue happens in a completely clean vanilla game (no mods, no CC, fresh user folder).
I also tested with my mods enabled (all updated), and the crash still occurs in the same way.

The save worked correctly in version 1.117 and started crashing after updating to 1.118.
Other saves and new games work fine.

Let me know if you need any additional testing from my side.
