When i was on my friends minecraft server i came across a one chunk hole in the ground with even the bedrock missing. My friend who was on his xbox came to see the hole and when he arrived at the location all he could see was the normal terrain, he even jumped up onto the missing blocks and on my screen appeared to float. I then decided that it was just a visual glitch so i ran forwards to leave only to fall into the hole in the ground taking void damage as soon as i submerged below where the blocks were supposed to be. I then died in the hole a few seconds later and lost all of my stuff
