You have to copy the entire content of the save folder. The .global file is needed to show the previews in the loading screen.
i highlight and click on the "www" folder and it doesn't work, it used to though
Do you know any other way to do it. Cause I have the same issue where it doesn't work that way.
i figured out another way, highlight the "www" folder right-click choose "copy" then go underneath all the folders in the new version, don't highlight anything, right-click and pick "paste" that should do it
