Hello, I'm encountering an issue with my game screen sticking on loading screen when I try to play with a household. I've attempted bulldozing and moving out my Sims, but unfortunately, it hasn't resolved the issue. I've also tried deleting and reinstalling the game, starting with a new household ( which loads without a problem), However, whenever I attempt to play with my desired household, the game gets stuck on the loading screen. Interestingly, I can hear the sound effects indicating that The Sims 4 has finished loading. Edit By Crinrict: Removed all-caps from title [Luth: edited title for easier searching]

@NaomiGotTheSims Please install the cc fix for milestones: https://www.patreon.com/posts/mod-milestone-81237568Looks like you removed an custom object from your game that gave milestones. This is causing issues with the game.

@katemillion Could you upload the lastException file ?

Since you can't upload XML files, you will need to either c/p the entire text or create a rar file to upload.

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? the newest
What expansions, game packs, and stuff packs do you have installed? Almost all packs, some kits
What happens when the bug occurs? I can get into my household when I first load up my save, but once I try to go to another lot either via travel or build mode the game will crash or be stuck on an infinite loading screen. The same thing happens in other saves that I have not opened since the recent update. Even tried taking out mods and disabling them but still nothing.
What do you expect to see? My $1000+ game to actually work
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes, am in the process of 50/50ing out mods to find something broken but even w/o them this occurs
Did this issue appear after a specific patch or change you made to your system? Yes, the most recent broken patches
Please describe the patch or change you made. the latest ones
Most recent last exception references "T:\InGame\Gameplay\Scripts\Server\elements.py" and "T:\InGame\Gameplay\Scripts\Server\developmental_milestones\developmental_milestone_tracker.py" but I do not know what this means and I cannot find these files. Any help would be much appreciated, this broken game costs more than my PC. I'm worried my saves may be corrupted but this has never happened to me before so not sure what this looks like.

@katemillion I've merged your post with the main thread on this.

Please install the mod listed in the solution post to fix this error.

This is caused by removed items that gave milestones.

@katemillion Could you try if the cc/mod object fix helps you: https://www.patreon.com/posts/mod-milestone-81237568

Looks like you have an issue with milestones from an cc object that got removed.

Hey I’ve the same problem and it’s driving me crazy for the past days after the last update. How did you manage to fix it?

@miasonbibi There are multiple possible causes of this. One is outdated mods. Start by testing vanilla to see if that's definitely your issue: https://answers.ea.com/t5/Mods-CC-Issues/INFO-How-to-Use-Mods-and-CC/m-p/13439356#TestVanilla

Hi,
I have a question about the MOD you inflicted. How did you do this correctly? Where did you enter this MOD correctly so that it works?

After the last update, my active household wouldn't load. I would hear the loading sound, but the loading screen was endless. I removed all my mods and ran into the same issue. I tried repairing the game and loading it into another family first, but I ran into the same issue. I've also tried making a new game and, loading the family off the gallery, and recovering saves. I figured out the issue is on a specific sim, as the game loads fine when I remove her. I even tried loading a new game using a kid version of the same sim, but every version is broken. When removed from the household and added back into the live mode, she turned invisible. I could still control her, but I couldn't see or click on her. This happened in all outfits. Eventually, the endless loading stopped, and I started getting an error code, which I've attached. She is my matriarch, so I would really love to save her!

I have every pack and am playing on a Mac.

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

Best is to delete the ones you have, then trigger the error and check if new ones are created.

If that is the case, please upload them to a new post in this thread.

Please either create a .rar file to upload or copy/paste the content into your post.

Deleting the file won't fix your issue. Uploading the file is meant for troubleshooting.
