Upon loading a world from a previous version one may find:
Double layered blocks may only have one block loaded(A product of code-crunching, performance increasing methods that is highly experimental but works nonetheless on reducing resource usage, mainly pertaining to a memory compression in the compressed .jar file) Here in this screen capture image I have enclosed an issue that not only renders the door immovable, but corrupted. I fully understand that this is a development version of Minecraft that will not be 100% perfect, but is the player's responsibility to report any glitches promptly to the development team at Mojang. EDIT: Lost the door in question, to recreate it go into a previous version of Minecraft and create a door(door frame optional) and save, then head to the current version of Minecraft, and apply a redstone signal to your door that may only partly exist.
