This was for the people who didn't know. As you can probably see on the forums, people are asking how to delete the giant obsidian oblisks from the nether reactors, how to transfer worlds from survival to creative and so on. I told them I would make this video, so I did. If you already knew about it, I do not see a reason as to why you would need to comment about it. Why not move on instead of trying to cause problems?
