The game crashed and when i started again game, my house was missing and all my stuff!

Hello, the story goes like this.. i entered my 3 levels-house , then.. i heard the classical noise of creeper somewhere next to me ( it was above me in the end ) tsssssssss, and then a creeper destroyed some part of my house and 3 chests with a lot of treasure (diamonds-minerals) and hard work(contructions etc) inside! So.. all good till now! when i went to gather the things that was here and there surrounding all the place the game crashed (first time). When i started the game again, everything around my house was still there even the sea (as my house was built in the surface of the sea) but my house was missing!!!!!! ALL OF IT!! 3 levels!! Like David Copperfield was there and make my house invincible!!! I have somewhere in a file the crash report, is there anything i can do to recover my house again? and of course all my stuff back?
