My profile will fail to load and I will lose all my items, Diamond armor, enchantments, weapons, all items.

I'm losing all my items after I save and quit. I'll come back to play and everything that I've worked for is gone. Rare, hard to get items gone. This has happened twice. by the time I recover from being robbed it's all gone again. I would like to get my items back but at the very least I need to keep this from happening again.

If this can't be fixed I don't know why I would keep playing.
