[@IceHeart] Yeah, it is a new feature since we can delete pm's. If their name isn't there anymore it means they deleted it. Whatever you send from that point on will not be delivered to them because it is no longer in their pm box. It's not a glitch. You would have to start a new pm if you want a response. (You still have it because you haven't deleted it obviously but yeah, they won't get it because they don't have it.)
