I made a world that me and my friend play in, I exited the end through the portal like I have countless times before. I instantly died to fall damage, I am very very shocked. I worked on getting the items I had on me for at least 12 hours. After I could not re-spawn, and the screen was stuck saying "generating world" in the bottom of the screen, I exited to the Nintendo Switch home screen, closed Minecraft, and went back into it. I reloaded the world and my stuff was not in the end, my bed where my re-spawn point was, nor spawn, It was all gone and I would like for this issue to be resolved. If it was intentional for things like this to happen, I would greatly appreciate if I got told how to make it not happen anymore. Thanks.
