I created and worked on this singleplayer world at another location for a while and properly saved and quit to title. I then went to my current location and xbox and loaded onto minecraft (no problems with syncing user data) and opened up the world only to find about 1/2 of the progress from creating the world to what i had previously "saved and quit" with was there. As if the last 4 or 5 hours of progress never happened. Please fix this its super dissapointing to see hours of progress gone in the blink of an eye...
