I go back in my Nether after a bit of playing and then most of my work is gone. I did a little test to see what would happen if I left the game to see what would happen when I go to where the place resets then leave the game and come back and then after that everything I made just reset and turned into a wall. This is a problem mostly because of bridges that I made vanishing. Thank you!
