What’s Wrong With My Sims 4 Game??
egwarhammer
If you’re asking this question, chances are, you’ve run into either a broken mod, broken cc, or EA errors. Any error can generate a lastException in your /Sims 4 folder.
Players with MC Command Center or Wicked Whims are notified of them in game. Players not using either mod still get them, they just don’t know, unless something gets really strange in game, the game crashes, or the player actually sees the lastException file(s) in the Sims 4 folder.
Broken CC is the number one cause for lastCrash files. Outdated UI mods are likely to show you lastUIExceptions. The first step to fixing either is to check download sites and make sure your mods and custom content are ALL up to date for the current patch. Anything can break, depending on what EA does to the game code.
If you’re interested in doing some of your own troubleshooting, reading the LE is where to start. You can open it with a text editor. (Note I said “reading,” not “understanding.”)
Recently we’ve been seeing several of the same errors over and over on Deaderpool’s MCCC Discord. So, here’s a partial “what’s going on” rundown, up to and including the 1.41 EA patch.
Event goals (parties, dates, etc.) are broken. EA will have to fix them. If you look at the LE, you’ll see this:
<categoryid>situation_goal_multi_sim. py:63</categoryid as well as this:
Exception raised while trying to run a test event in test_events. py: (TypeError: ‘NoneType’ object is not iterable)
The workaround is to have events without goals, and to hold off trying to complete the Party Animal aspiration. (Play other sims, or choose a different aspiration, for now.)
Apartments are broken. Details here:

Protest signs occasionally throw exceptions in San Myshuno.

Broken ghosts are showing up in some “older” saves. Here’s how to fix those, by Nies.
resend_at_work_infos: caused by broken ghosts.
Fix:
Give all households without a name in the household menu a household name.
Additional: Use MCCC’s Mailbox -> Hide households -> Hide said sims in order for them to not show up in the “Other Households” menu anymore
Pets are causing get_focus_bone errors. Tysakasa came up with a partial fix, using MCCC’s Autoscan function.
For those who are seeing a lot of error reports referring to 'get_focus_bone’ we believe we have found a solution to the problem until EA releases an update to officially address this.
You will want to open up your mc_tuner.cfg file found within your MCCC’s folder and add the following to your list:
164920,pet_Investigate_SniffNewObjects
If you do not have a mc_tuner.cfg file inside your MCCC folder, download and place the file there. Then delete your localthumbcache.package in /Sims 4.
If this error persists even after adding this line, please let us know in detail what happened leading up to the error. We may ask for your save file so we can test and look to see what else could be added to help smooth things over.
Traits break often, and a lot of them are. If you see a line like this:
Caught exception loading reference. RefName: 158875 Manager: InstanceManager_interaction. TunableReference is set to a value that is not allowed by its class restriction.
You probably have broken traits or aspirations. "RefName" is what to look for. LONG numbers there point to mods, more than to cc.
Some error messages will show you WHAT broke, like this:
AttributeError: 'pbox_notebook_tuning’ object has no attribute 'get_focus_bone’
But, there’s an exception, sometimes you’ll see mods listed that use injectors, and are only being “caught” by the eror-catching in MCCC or WW. It’s always a good idea to CHECK any file you see in a lastException, but some are likely to be fine. It depends on where and how they show up.
More to come, as time permits. Hope this helps!!
