Ok so I had opened up a world that I had for over a year. I hadn't been in it for months. On late Tuesday night into early Wednesday I had been playing it...getting a few achievements from the update that brought dolphins, treasure,ect. I saved and exited the world. I try to get on late Wednesday and the world is nowhere to be found....it's missing. It's as if the game deleted without my consent. Everything is gone....my house, two fenced in villages, a farm, a livestock farm, end portal, the nether....along with the multiple chests I had filled and my enchantment table room/brewing station. The world is completely gone. I want it back!!!! This happened on xbox one I should add. (Also, I already made a post about this but was redirected here by whoever was handling the issue)
