This is one problem, not more, I write all what happened to help.
I want to play today, and the world loading every time wrong /as you can see on the video/
or loaded one time wrong and saved this wrong world.

We played many many days on this world with my friends. Now all is gone.
Where is now nothing, there was our huge animal farm. And there was the farmers, and fields with food, and waterfall....and many many things. Now all gone. We can't fix this, that will take weeks.
Please give me back my old save game, before 28.04.2018. We played last time 2 weeks ago I think.
We don't want to start again, so without this world the game is pointless to us.

Before I start the game I checked, this was the newest version. Last time my xbox updated beta version without I want to beta. We not played with beta at all, I deleted straight away. I newer ever want to play beta, that was your fault. That time I deleted minecraft and install again on my xbox, and I got back normal minecraft. After we played, so there was no problem. Nobody use/used beta, everybody use normal minecraft. on xbox, pc, android.
The world is on my xbox one s. On the video you can see how the game start, how it looks now.
Please fix this issue to us.
Thanks
