the game wont load after create a sim

If playing with mods and custom content, move your mods folder to the desktop, clear your game cache and delete the localthumbcache.package from the Sims 4 folder to help with troubleshooting.

Try playing the game again to test without the mods folder. If it loads okay, it may be that some of the mods/cc have become outdated.

How to Delete Cache Files

Custom content can become outdated with most new game patches. If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced. EA/Maxis aren't responsible for broken mods/cc. It's up to the creators to fix.

Disabling or turning off both mod/cc options isn't enough of a test.

Try the 50/50 method:

1. Move all the mods and cc out into a temporary folder on the desktop.
2. Move a few files back at a time. Load the game to make sure it loads and everything is good.
3. Delete the localthumbcache.package from the Sims 4 folder.
4. Repeat steps 1 - 3 till there is no more files to check.

** While your testing, don't save the game. If you find any problems, delete the mod or custom content file.

You mention you're missing your save files and that families keep disappearing? We have some tips that might help. Please forgive the wall of text. It's quite a read, but hopefully it can help you find your saves, get them to work and to help find your families.

If you still have your saved games in your Sims 4\saves folder -
[C:\Users\Username\Documents\Electronic Arts\The Sims 4\saves]

It may be the game isn't reading the save files correctly. Have you tried renaming your saved game file?

To rename your save, remove the version number. - .ver0 or .ver1 by deleting the .ver1 on the end.

For example:
Slot_00000002.save.ver1

Rename it to:
Slot_00000002.save

You may want to give it a different number if you already have a save 2 in your folder. The game should then recognize the save file again.

-- If you have an old auto save file (Slot_00000001.save) it's safe to delete as the game doesn't use it anymore.

If the above doesn't help, Crinrict has some very useful tips on saved games disappearing:

--- Regarding missing families ---

If you're missing any families, have a look in the Library as a copy of each family created gets saved to the library every time you create a new family.

Or check Manage Households, it's up in the right corner fo the map screen.

In the My Households tab (which is automatically selected) you should be able to find what families are in-game and what world they are in. To play a family, find them in the world they are in and select them to play.

If they aren't in Manage Households, maybe you saved your game playing one household and then switched to another household before exiting the game?

If that doesn't help, click Load Game to see what other saves you have. Select a save to see if you can find the missing family, through Manage Households.

Please Note: Sim families from another game save cannot interact with another Sim family from a different game save. To get them to interact with each other they need to be in the same game save.

-- To get the families all into one game save, go to the main menu and click Load Game for each of the families you want to save. Save the family and their house to the library and place them into one game save.

** Important Note: **

If you exit CAS or the game before the household is finished being created, you loose that family and will need to start over.

However if you've already created the household, but not placed them in the world you need to load the game and either click the Play button to continue from when you last played, or Load Game button to select the household.
