Good morning! I have been having trouble creating a copy of my 900 MB world, And I want to create a copy since some months ago. Something I gotta say is that the copy always gets stuck at 40% and freezes there, and after some minutes, It appears a message that says: "Failed to create a copy of your world" (btw forgive me for the lack of quality in the photos I uploaded, and also, forgive me if I made any writing mistake, cuz english is not really my country language).
Thank you for your report!
