I killed the ender dragon and went through the portal on accident.  I came back to get my xp. I then went back through the portal, and then I heard the death noise and the screen turned red and the generation froze. I loaded back in, and my stuff was gone. I went back to the end, and my stuff wasn’t there. I went back to the stronghold, my stuff wasn’t there, I then allowed myself to get killed and went to world spawn, my stuff wasn’t there. PLEASE HELP ALL MY GOOD STUFF IS GONE. I can’t attach the clip of the glitch but I’ll try to comment it
