My world loaded with my house split by a forest and all my chests empty

In my private world Ziggyland, our computer crashed. When we restarted and reloaded the game, there was some kind of error message saying that the game couldnt load and then when it did come online, it was a weird colour like we were trapped in something. Then as it cleared up, we were in a forest.  Our main hidey hole was split on either side of this forest that sat within a mountain (where our hidey hole was).  everytihng was shifted around, but the place where stored all our assets had all the chests empty. Is there any way you can reset the world back to where it was yesterday or earlier today even? Its a devastating loss for my kids and me. Thanks for your help.
