Thank you for posting on the Xbox forums.

I understand that one of your Minecraft worlds seems to be corrupted, and you are unable to access it. Minecraft worlds are at risk of being lost, Mojang support recommends to back
up your worlds from time to time. This will help prevent the loss of worlds. I would suggest reaching out to the Mojang support team for
more information and support on corrupt worlds. I hope this information helps!

Hello NFFC Sissons XD,

Thank you for posting on the Xbox forums. We understand that one of your Minecraft worlds is no longer appearing on your list of worlds. Minecraft worlds are at risk of being lost. That is why Mojang support recommends to

Back then when the Xbox One Edition (the Minecraft with the "Xbox One Edition" in the name, not the new "Minecraft" for Xbox One) was released, there was a short time, where you could buy "Minecraft Xbox One Edition" for a reduced price, if you owned the
original Xbox 360 Minecraft digitally.

Xbox 360 Minecraft and Xbox One Edition Minecraft are two different things. Like having a vinyl record of a music album and then having to buy a CD of the same album. Or having a DVD of a movie, and having to pay for the BluRay version of the movie.

However, the Xbox One Edition can't be bought nowadays anymore. Have you had the Xbox One Edition digitally, you would get the "Minecraft" (without the "Xbox One Edition" in the name) for free.

You can however transfer your Xbox 360 worlds to the Xbox One, if you somehow got hold of the "Xbox One Edition" before it was replaced by the new "Minecraft".

To do that, start your Xbox 360 Minecraft and make sure it's on the latest version. Then use the menu entry to upload your world to the online cloud.

Now start up Minecraft Xbox One Edition and import your world.

With your world in the Xbox One Edition, you can then start the "new" Minecraft on the Xbox One, and import your world from the Xbox One Edition to the new Minecraft.
