Ok.... So I went into a stronghold and cameout with a bunch of good stuff... diamonds, gold redstonee, lapis, iron bars, iron doors, three types of stone bricks, four stacks of books, three enchanted books and more... and I got back to my house. I was putting my stuff into my chests when I realized I needed more room. I broke my jukebox, and suddenly the screen froze. Then it wen black and a screen came up after a few seconds with an error message. It said Minecraft had crashed. I closed the window and restarted. That was when things got... complicated. I spawned where I had left off... AND THE WHOLE CHUNK I WAS STANDING IN RESET WITH ME! A valuable chest was gone, along with a quarter of my house! And, annoyingly enough, a tree had spawned in the space where my floor once was. I had a perimeter wall, and a quarter of that was gone too! As I soon discovered, half my basement was filled in, a second valuable double chest was lost, and even part of my small tunnel network surrounding my basement was gone. I resurfaced and turned around to see my sixteen sheep running everywhere: in the remains of the house, on far hills, anywhere but in their now-broken pen! One of every color sheep, gone. Naturally the jukebox was missing as well. What worries me most was the two chests. I don't remember everything in there, but I remember two stacks of redstone and two stacks of lapis, along with some diamonds! Is there ANY way to somehow get everything back?
I mean without going into creative and fixing everything. I seriously need those chests.
