Re: WHITE SCREEN ON WORLD MAP

@Maik4467  When you moved the Sims 4 folder, you moved your saves with it.  The saves are still intact in that folder, it's just that the game can't read them.  You can put them back later, once the game is working again.

Please run that dxdiag and attach it to a post.  I'd like to see if there are any system issues to address.
