Synchronization bug of an update

when I played a minecraft, m 'a console closed the game so that I made an update that I could not refuse. As a result of that the next day I wanted to come back to me part and I received an error message about world synchronization or ca corruption. I guess this and due to the brutal closure of the game because of a beta update not expected. But I wish I could get back because I spent several days on it.
