I had gone to the moon and set up my base, and realized that regular torches don't work on the moon, so I went back to the overworld, went to the nether and grabbed some glowstone for glowstone torches. When I went back to the moon, I got out of my lunar lander, and when I went to check the inventory of the lander, everything was gone, including my rocket and rocket pad. Any ideas on how to fix this? I tried immediately exiting the game without saving, but when I went back in, the inventory was still blank.
