Hello, this issue pertains to the fact that your game has crashed. You will not be able to retrieve the land, and this will be stuck with you forever, as long as the world lasts. When your game has crashed at one point, the code for the chunks, for example, 0 1 2 3 4, has failed to save fully or at all, and the game sees 0 1 1 3 4, or anything in that nature, and replaces the chunk entirely. The only fix for this solution is to have a backup of your world.
