Re: I can’t move sims in from manage households

@ioannabella   Hi!  That's really weird and frustrating.  Does this happen for any household?  Are you playing on a PC / Mac or on console?

If you're on PC / Mac, the first thing I suggest is a game repair.  Exit the game, if it's running.  Then go to your game library in Origin, right click on the game and click repair  OR if you're on PC and using the EA app, click the game, click Manage and click Repair.  Either way, let the repair run for all packs, even if you get a prompt that the game is ready to play.

Also, if you're on PC / Mac and using any mods, move your Mods folder to the desktop, delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing.  Then open the game to see if you still encounter the problem.
