Game stuck in "Game Loading in Progress"

Wow thank you so much I’ll try it now and let you know if it’s successful! Been trying to get it to work for three days now. 

Ive FINALLY fixed it and I’m beyond happy. I think it was the roommate mod I installed a few days ago and it must have been outdated or bugged. I’m glad I didn’t have to get rid of my family as I’ve been playing it for 4 generations! Thank you so much for the help!

Glad to hear you fixed it and think you for the feedback which mod was the culprit for you.

I don't have any mods or CC and I'm still having this issue on lots downloaded from the gallery -- the lots I downloaded have no CC or mods either! 

@kfyy
It may happen if this house was created with too much MOO used or has a lot of paintings based on CC paintings. Turn on MOO in your game before you set up such a house in the game. Check also how much MB has such a house "noCC". Those filled with these paintings can have even more than 1 GB. I saw one who had 6 GB. No wonder the player who wanted to use it was in trouble.
 I personally do not recommend such houses.

I had the same problem and after 2 days of figuring out how to solve it, I finally got the formula 😃 ! I tried various of steps that I found on the internet such as removing my Mods (but you're free to remove some of your outdated mods just to be sure) or moving my household then moving them back, nothing worked out for me. If they didn't work out for you too, try mine. NOTE: This process does not include removing your cc & mods.

1.) Open your Sims 4

2.) Share all important Households/ Lots/ Rooms from your library to the Gallery (NOTE: You MUST be online to make this possible)

3.) Save & Exit your game.

4.) Remove all Tray Files from Documents\Electronic Arts\The Sims 4\Tray

5.) Open your Sims 4 again and Voila! (It worked for me)

P.S. You can now save your Households/ Lots/ Rooms from the Gallery (Profile: Shared Items) to your library. And that's it!! 🙂 Hope this one helps!

Hey! I have a problem that is : game loading in progress, but i don't have any mods/cc in my game, it suddenly happen to me when I'm playing, idk how to fix thisss! I'm scared if i get out of my game without saving, i lose the whole entire game! How do u fix thiss? 

@alikanasya   Try to save the game using the option: Save As, then exit it. If it is possible try to go to another mode, like build mode, and try to save there.

But if you exit the game without saving you will only loose your progress since the last time you saved. You can load any of your old saves from the Main Menu if you name them using the option Save As, which is why this saving method is recommended; and also to save often. If you use the options Save, the game will still keep the five last times you saved: click on the button called Recover Save on the Main Menu, and choose the newest one to load.

When does the game stop loading - when you start it, go into a household, download a build, try to save?

When you have exited the game you should rename your The Sims 4 folder, to let the game create a new one and see if that loads better. Please follow the linked description. Don't move back your old files until you have successfully loaded the game in the new empty folder and played around a little to test the loading screens.

If that doesn't work, please post your dxdiag. Here is how:

Yes! I thought I was the only one because I tried to fix it by looking on youtude and it won't let me enter build mode

I have the same issue it just happened to me and I wanted to build and or explore my worlds but it said the same thing!
