For those of you having trouble getting the Ripper to rip (yes I was one of you ) Select the Ripper in drop down Planet menu ( left side of game window ), select "Teleport" from Ripper menu. New menu opens on right side of game window, Teleportation coordinates on top of menu, Ripper on/off on bottom of menu. Turn the Ripper "on" ( Yes now that I found that, I do feel a bit stupid )
