loss of some progress Better Together Xbox One Version

when you guys went from version 1.2.1 to 1.2.2 my progress on my creative world ive been building for 5 years. the game didnt save/sync my progress to the cloud when i went back into it. a few of the things ive built or done work towards were undone. i had completely laid the floor down to my target store. and that was all reverted back to grass blocks. i had completely dug and layed out a massive ground area for my upcoming airport and that was reverted back to a save at some point ago within the last 2-3 weeks ago roughly. is there anyway to retrieve my most current save. somehow it dont exist in the cloud. only a save file from before i had layed ground and the target store doesnt have a red floor and is back to grass block flooring instead. my world map I spent hours to get each piece to to my world to place in my world wall map in my city hall that doesn't exsist anymore either I had to start that over again too. my target parking lot was completed but now its back to halfway done. is there anyway for me to get my latest progress save back. that's a lot of work to redo for me. it took me 1 week just to get my airport ground dug up and layed down. if not could you please apply an update that allows us to back up save files of our worlds to USB since the cloud service isn't reliable. (Note: this is for the Better Together version for xbox one) (Note 2: please add the option to turn on/off other players abilities to pour water/lava specifically maybe a subtab option under the can build/mine option. we need more and better control over other players abilities within our worlds to help prevent griefing better)
