Minecraft world lost on xbox one

Hello, one of my Minecraft worlds got deleted... I was playing and all of a sudden my xbox lost connection to the internet. Had to restart the xbox so I did, saved the Minecraft world, and when I logged back in the world wasn't there for some reason... The weird thing is that that's the only world that got deleted... I remember I got some type of pop up when I started minecraft after reseting my xbox that said something about finding the worlds that I had on the cloud or something like that... Thank you
