I cannot seem to resolve this error. It doesn't allow me to load a household. I have removed all mods and the games worked fine but I cannot go through 1000+ mods retrying each one to find the faulty one. My mods are all from Curseforge and are all up to date. pls help.

I am having same problems. & I have BE, same as the above.

Having the same problem. I have all the mod trackers and everything seems fine before I go into game. I've been putting mods back in one at a time all day and can't seem to pinpoint the problem. It's not the MTS food group mod, it did give me trouble yesterday but I don't have it in today. I've repaired the game and I still don't know what the problem is

Download Better Exceptions, load the save again, and the name the script file of the offending mod will be at or near the bottom of the Last Exception. The culprit will usually be a script mod whose creator was never expecting EA to ever change arguments for the function "load_data_into_class_instances" because it hasn't been changed in a decade.It could be any old script mod which adds or modifies interactions, the reward store, buffs, traits, or modifies a sim's needs. This will notably affect almost every single old mod made using Mod Constructor.

I have tried Better Exceptions but it only comes up with the error in the subject, it says no mods are the cause. I have removed a few mods off curseforge and cleared my cache in steam but that doesnt seem to have done anything. However Better Exceptions is now showing a different possible cause, any ideas on how to solve this one? thank you

The August patch broke many, many script mods, with this being the symptom, and these are still the ones most likely to be your problem. Use the Previously Broken mods and CC for many (not all!) mods that have no updates. Use “Updated” in the Broken/Updated Mods list for patch 1.117, but note many are not yet updated or cleared in the current list.

Hi, The same exact problem is happening to me as-well, this is my screenshot from BE, My households DO NOT load and just spit me back into the world selector
I have no clue what "main\game_handlers\tuning\tuning_class_injection.py" is.

kaenotkay Do households load if you rename the mods folder?

I have the same issue with “main\game_handlers\tuning\tuning_class_injection.py” being the issue? Better exceptions doesnt tell me anything else than that

claimME See vanilla and 50-50 testing. Note that you have to leave in injector/library mods when you're testing mods that require them.

I'm literally having the same problem! I thought it was lot51 that was the problem but it wasn't. That's my only problem right now and I don't know how to locate the bad mod/script file.

I'm just updating and getting the same error from BE:

main\game_handlers\tuning\tuning_class_injection.py
Which mod is causing this error? Appreciate your help!

MrPregnantCatBat BE is currently giving false positives. See Broken/Updated Mods & CC. Fashion Authority is cleared for this patch.

Same issue, using Better Exceptions. Mine was Lot51 though both core and Fashion Authority, and Choose High School Classmates all from Curse Forge. No issues with WW this update for me. It seems like Fashion Authority and Lot51 in general always breaks my game every update though so I just uninstalled those by habit.
