Hello! I have this World Save that I can't open, and doesn't appear in the World listing anymore. It was a superflat creative mode world with just the LOTR mod. I think something in it got corrupted, because even when I copy paste the Region files into a brand new world, they won't load, and that world disappears from the list too.
Any help or troublesheeting to retrieve the builds that are inside would be so appreciated!!
