Removes all items.

I updated to the latest snapshot. Then the next day I downgraded from Snapshot 14w17a to 1.7.9 and when I went into my world all of my items were gone all items from chest, enderchest, and my inventory all gone. It was a LAN world and when my friend loved on with the snapshot before I downgraded all of his items were gone. If it is possible is it possible for a developer from Mojang patch this and have it so you get you items back. I provided some files if it would help.
