My server crashed last night while one of the members was using worldedit to cut and paste a large portion of the server. The clipboard was obviously cleared, and the large chunk of land was then not recoverable to his knowledge. Today I got on with the intent of fixing this, but the server autosaved a new save file after everyone had logged off, so the save file did not include that section. Is there any other way to recover this previous version?
