My Minecraft Xbox 360 edition disupdated?

I just loaded my Minecraft when the update mesage showed up so I updated it, but in the middle of the update my inernet diconnected and my Xbox asked me to check my connection status which I did. When I reopend My Minecraft It was way older, they had only just added The End. I went to one of my saves and when I spawend I was in a completely differnt world and all my stuff was gone. When I opened the creative Items menu alot of the Items had been removed including emerald. How Can I Get My Saves Back. QUICK!

Added (1). I opened a few more saves and it keeps generating the same world for every old save!

You can't get them back unfortunately. When you reloaded the map, it deleted everything that wasn't technically in minecraft at that version. You have to install the update and just start over I guess.
