We were in a Spruce forest when I (Player 1) encountered a "invisible wall" myself and other mobs (chickens) could not cross - but Player 2 had no issues with the "invisible wall". I exited the game and re-loaded it, hoping to eliminate the "invisible wall".

To my shock, when I loaded the game I found myself FALLING IN THE SKY ABOVE THE CLOUDS. Needless to say - I died when I finally hit the ground. Player 2 immediately logged into the game - he was on the ground just as he was when we exited (fairly close to me) AND he could not locate ANY of my stuff, even though it was all right there.

So, not only did I die - all of my stuff was also lost and there is no option to "Exit without Saving".

This was not an issue prior to this week's 1.8.0 update on XBox One console.
