I’m not sure what would allow me to reproduce it because I’m not entirely sure when it happened. I was playing splitscreen and I, player one, was away from the area but the other player was nearby and saw the hole in the water. I also noticed around the same time the entities we had, animals and villagers, wouldn’t move or give xp when killed by player 2 if player 1 was a few chunks away. We’ve had caves and cliffs turned on since world creation, and as far as exporting and importing I’m not sure how to do that but i could if it would help.
I was about to post a vid when I noticed it updated and it’s working now
No, just running vanilla.
I don’t have the exact date but i created the world 13 days ago based on screenshots I took on xbox, it’s not custom or anything.
