I was on my world, using some player launchers I had set up to get around quick. I was trying to get away from all my old projects, so I set up a player launcher around X: 29,900,000 and l launched myself. I fell through the world when I landed and died. I learned off the wiki that this was the "far lands" glitch. I hate this glitch- it cleared me out of ALL of my items- including a few diamond blocks and the enderdragon egg. I know you've sort of dismissed this bug at mojang, but I think it NEEDS to be fixed.
at least make the world loop at that point until you've fixed it for good.
