As the highest level Link play on the server (that's all I play anymore, actually), I have never had this happen to me. What Luna said about this bug is true. Accidental ghosting while the hostie being "held" happens. However, it does not rescue the hostie. I have personally never seen it happen.
I am very curious if that actually happened for you, Arctic, because I have never seen it happen with Blade Master nor Link. Grab evidence of this happening if you see it again and throw it in here.
