I was next to the end portal and I had about 2 months worth of items in chests around it. I put an enderchest down and put my stuff in it, then I destroyed it and my game completely crashed.

when I logged back in, the end portal and all my stuff was completely gone, and the whole room was filled with stone!!!

I restored it but I lost a good 5 days Worth of mining and crafting.. Please fix it!!!
