Re: My game crash when I try to exit the CAS or try to save a family
@MissEunhye Do you use OneDrive? If so, that may be the issue, or rather OneDrive's attempts to sync the Documents folder may be the issue. Try pausing syncing and cancelling the current sync:
If that helps, make a copy of the Sims 4 folder in Documents\Electronic Arts and store it somewhere that OneDrive doesn't touch. (An external drive is ideal, but you can put the copy in Downloads in a pinch.) Then stop OneDrive from automatically syncing Documents:
Or, if you have no use for it, unlink OneDrive, which will keep it out of the picture entirely.
