Minecraft – How to generate a flat stone world on Minecraft XBox

Until the update is released, it's not 100% certain, but probably (sadly) no, you cannot.

You will get access to many of the new features, such as Endermen, enchanting, creative mode, etc. But probably not the terrain-related features you mention, such as Strongholds and Abandoned Mineshafts.

The reason is that these features are implemented by changing the terrain-generation algorithm. On the PC version, this means that new terrain features only appear in new chunks, generated after the update is released. But in the XBox version, worlds are generated all at once, on world initialization.

This should not make any difference what so ever as clearing the cache only removes temp files and old files that you have adjusted. Save files should not be touched and they can't even be touched by the cache. These problems are not related to each other.

Stated on the xbox FAQ is :

The most important part of clearing the cache is knowing what to expect. All downloaded game updates will be removed. So if you have downloaded an auto-update for a game, in order to play it on Xbox Live you will need to re-download it.

**** User game saves, profiles, demos, videos, etc. are not deleted during the process.**

Note the last sentence.

This however does unfortunately mean that if you cant seem to get to your save file in the minecraft world it has been lost. My guess would be that something went wrong while re-downloading the updates and that during that process your save file got corrupted. Minecraft then automatically fixes that but in your case that meant that it created a whole new .world map.
