This unknown item looked like the disc strad to me, but whenever you reload the world, it looks completely different. You can only get it in creative inventory because when you enter the command "/give @p item.glow_frame" in the chat it says "Invaild command syntax: no such item.glow_frame exists with that data value" so this item is broken and it is a CORRUPTED GLOW FRAME? MOJANG WHAT IS HAPPENING???
