Default Old save is throwing exception all of a sudden
Hey everyone!

I haven't played the game in quite some time (more than 2 years!), so before I first started it up again, I installed all the updates and checked if there were any mod updates too. Back then there were no error or exceptions, even with mods, but now a new "lastException.txt" file (or the old one is overwritten) is created every time I load up the game and into my main save:
Quote:
unique_object_service failed to handle on_all_households_and_sim_infos_loaded due to exception (IndexError: list assignment index (0) out of range)

What I already tried:
  • Remove all the mods, restore a backup of the same save (just in case) - didn't help
  • Delete "avatarcache.package", "localthumbcache.package" and "Resource.cfg" - didn't help
  • Load an older save - didn't help. The only save that doesn't throw this exception is the very first one that was created after the sims moved in.
  • Press "play", create a new save, restart the game, then load that new save - no change
  • Repair the game - didn't help
  • Rename the "The Sims 4" folder, start the game, close it, copy a single old save into the "save" folder and load that - didn't help

My PC's definitely strong enough to run the game (Win 10, i9, GTX 1070, 32GB RAM). There are no crashes and I didn't notice anything weird when I pressed "play" but I really don't want to play and have to deal with bugs caused by this exception further down the line.

Any idea what could be causing this and how I can fix it?

Here's the full log ("infobutton" tag doesn't work, sorry):

It sounds like you've tried most troubleshooting steps already. Have you checked if any mods are still causing conflicts, or tried starting with a completely clean user folder?
I removed all mods but the exception file was still created.
A completely clean user folder? What do you mean?

Have you tried BetterExceptions by TwistedMexi yet? The exception gets a little easier to understand if you use that mod. Maybe it can pinpoint you in the right direction? I do hope you'll be able to solve your issue

Sorry about the delay!
I downloaded both that mod and the "always testing" one by the same creator and ran a scan: It didn't detect any mod conflicts (of course) and the exception summary says the same thing as the exception file:

Possible Cause (Confidence: 10%): cpp_message

MCCC Version: Not Installed.
Mod Count: 0 packages, 1 scripts
I understand the "index of of range" part but what list is that?
