Hey there Victis!

Have you tried loading up the minecraft worlds that you don't recognize to see if they're perhaps your worlds just with different names?

If the worlds are definitely not yours, then it looks like your Minecraft data was lost.

As Mister Fizzle said, there have been issues in the past where Minecraft Title updates have caused Minecraft worlds to be lost. It's possible that this has happened (since a Minecraft update came out recently).

However, the loss of your Skyrim save seems to indicate that the process to move the data from your USB drive to your hard drive did not complete properly or errored during and caused the data to be lost.

I'm sorry that I don't have better news for you.

Access Application Data\.minecraft\saves. ...

1. Make a copy of the corrupted world folder & all files & folders inside, and rename it however you please. ...
2. Start Minecraft and create a new world, then save and close Minecraft. ...
3. Go back to Application Data\. ...
4. Cut the files (but not the folders) from the new saved world folder.

I've tried several other games, and they seem to each need to sync my data back to them, but they have all worked so far. Only Minecraft has had anything corrupted. Sad. That was a good survival world.

Sorry to hear you lost your world. However, if there's a chance you've played on that world on a different device there may be a copy of the save there. Please double check if you can

It’s a Xbox I’ve lost everything
