Nothing important, just found some holographic displays and didn't know if you wanted to delete them. They are underground and in the middle of the wild somewhere. Can't figure out how to put up the screenshot but the cords are -1.503/73.0069/91.968, under the ground a bit. I dug stairs to them.
For screenshot: Press F2 in game, to take a screenshot. Then find the minecraft folder on your PC. You will find a screenshots folder inside it. You can attach the screenshot by clicking the button "Upload a File" here.
thats for windows nebs. for Linux: Go to /home folder then press Ctrl + H, you should see .minecraft folder then open screenshots
