I've been playing on a new survival world just about nonstop for the past 2-3 weeks, today while playing I accidentally unplugged my Xbox and when I logged back in, the world was completely gone. All my other worlds were still there except the one I was playing on when my Xbox unplugged I tried to back up old worlds but it was nowhere to be found, I tried restarting my console 3 times to no success and I even uninstalled and reinstalled Minecraft  two different times. After trying just about everything I was devastated and in tears. I know that sounds pathetic for a 15 year old boy but i have almost 1000 hours in Minecraft and almost 100 in that world, i had just finished off the item sorting system and storage for my guardian farm and was about done with a 75x75 block pyramid made out of Prismarine. i had fully enchanted diamond armor and tools and i was very devoted to keeping this specific world in pure vanilla survival and not switching to creative and cheating like i normally do. i don't know how this reporting bugs thing works but please Mojang, help me get this world back. i have all my account information ready if you need it and can send it to you at any time as well as any other information you may need
