Hi Mojang! I Would Like To Report Another Bug In Java Edition. So Basically Go To The MC Launcher And Choose A 1.8 Ver. Now Create A Superflat World And Save & Quit. Then Choose Newer Snapshots And Load The 1.8 World Then Go In To Spectator Mode And Fly Underground Then Switch Back To Creative Mode & For Some Reason You Can Build Under The World. But Normal Superflats You Cannot Build Under Bedrock.

Up There.
