My son has been working on a world for almost a year flawlessly.  The world is always saved properly in the options menu before quitting the game.  In the last 3 versions of the game release when trying to load the world it fails to load.  It throws this error:

"You are out of data storage space and Minecraft is unable to save your progress!  Minecraft will return you to the Main Menu to clear up storage space.

However, we have plenty of storage space as it doesn't even show more than a quarter of the usage on space.  We only have 2 worlds, both are under 1GB in size each.

If you try to load the world a second time in a row the second error says:

"There was a problem loading this world."

Sometimes, randomly, maybe 1 out of 20 tries the world will load just fine and he can play and even re-save it, but then the next time he tries to load it, it's the same 2 errors above.  The first is always an out of storage space error and the 2nd is a problem loading the world error.

It's not a world size issue as this world is smaller than a 2nd world he created after this problem started.  So something with the world / game is somehow messed up and since the files are stored in a format that's different than the rest of the OS's supported, I can't load it to see what's going on and better identify the bug.

How can I get this issue looked at and see if there was a bug introduced in the last 3 versions to be resolved or at the very least have the world looked at to identify if it's some how corrupt and if it can be fixed.

Thanks much
