i played the game on another pc with different resolution, then i moved the savegames back, now i see only a black screen in the savegames preview, how can i fix it? thank you.
It should only be black in the preview, once you load the game if you save it over it that will replace the screenshot with a new one. The only way to actually get it back is to change the resolution to what it was but it won't affect anything in the actual game so I wouldn't worry about it.
