Stop trying to be funny. First off, I have seen the bug for myself and I can give you 100% proof it's no fake. Secondly, when the person prayed, the exact same thing happened to me, it looked as if it was the floor that way praying and when the camera angle is put as low as it can go it looks as if the prayer icon is floating. Thirdly, other people do see this, so it's definetely not lag. Whenever you or anybody else steps into where the person is, they also appear invisible, but when they step out they go back to normal.
