A few months ago, I made a new superflat world and started building stuff. I believe I was using version 1.8.8. I worked on it for a while, and then forgot about it. Today, I wanted to continue working on it, but since I am using a different computer, I copied the save folder over to the new computer. However, weirdly enough, even though I spawned with all of my stuff, the stuff I built was nowhere to be found (even when reverting to 1.8.8).
I then decided to use a world viewing program to see if I was just spawning somewhere weird. I used Minecraft Overview and found everything I built is there:
The home location corresponds to about (305, y, 70), so I teleported there and again found nothing:
Can anyone explain to me what is going on, or does anyone have any ideas for me to try?
