Game returns to manage worlds when I try to play with a family.

Do you have any mods or CC (custom content)? Try taking that out.
See this for more information: [PLEASE READ] Usage of Mods and Custom Content

I don't have any CC or mods. The problem started when my sim was at work as a police officer and was switching lots. Instead of going to the lot, it took me to manage worlds, and now the game is stuck this way.

Willing to share your save game ?

If so, please zip up this folder: documents\electronicarts\thesims4\saves and drop the file to this Mediafire-Link to upload.

Please make sure to name the zip file with your user name. 

Done! I use a PC as well, if that's relevant.

Thanks

I'll check if I can duplicate and get back to you soon

Hi @DryBird

which save game/family do I need to load

I didn't have any issues with the one I tried.

I'm not sure what it's called in the file, but the save I'm having a problem with is save slot 1(the automatic one)/save slot 2

For all families ?

Yeah, no matter which family I select, I get taken back to manage worlds.

Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199

You won't loose anything. Just make sure to not delete any files  and make a backup.

Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.

• Options.ini (or just re-set all your settings manually)
• Tray Folder
• Screenshots/Videos/Custom music
• Rest of the save games (leave out slot_00000001.save which is the autosave)
• Custom content like clothing, hair, skins, make up ....
• Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.
