I figured out how to fix it!!!

I’m not sure if this is a permanent fix but it worked for me. This bug happened to me in my main world last night I exited without saving and went back in a couple times, I got stressed and exited without saving and turned off minecraft so I can figure out later. Today I looked it up trying to find a way to fix it and couldn’t find anything, I logged onto one of my other worlds that didn’t matter to me, the same thing happened, I exited with the save and quit button. It brought me back to the screen that shows all of my worlds and the pictures were all grey for a couple seconds like they were loading. The picture of the world I had just exited was still the same as before I went in. I logged back into it and I was where I was before the bug, with all my stuff. I exited again and signed into my main world and I have all my stuff back, and I’m where I left off, not at spawn. I’m not sure if this is a permanent fix and I’m probably going to put all my stuff in a chest before I exit this world for a while just in case this happens again and this doesn’t fix it. 
 I should probably also mention this all happened on my Xbox one S
