I can't leave the vacation

@JohnDoe889  There's no point in moving the Sims 3 folder to the desktop and then back into Documents.  The idea is to move it to the desktop and leave it there, and let the game create a new folder, and only restore a few of the files from the old folder.  But none of your expansion or stuff packs should be missing after you moved the folder, whether you put it back or not.  Are you sure it's a pack that's missing and not a Store or custom world?  Please move the folder to the desktop again, don't put it back, load a new save, and see which packs are and are not loading.
