My player head is missing, the rest of my body and my cape shows, just not my head. It doesn't show while swimming, sprinting, walking, jumping, etc. My head also does not show while in "third person back" or in "third person front" in video settings. The head is also gone in the pause screen (where the save and quit button is to be clear). It doesn't show in the home screen, or in the skin editor. It appeared my other skins lost their heads as well. I don't know how to recreate this, it seemed to happen randomly. It did fix itself when I reloaded Minecraft.
