I built a KAS equipped orbital tug to de-orbit debris and help build space stations and I'm having all kinds of issues. I built it with the magnetic clamps, but those took too much power (didn't take into account they need power). So I EVA'd Maczor and had him replace all the magnet clamps with grappling hooks. Now either the attachment pointer doesn't show up (press H, click on a spot) until I reset KSP 2 or 3 times, or the pointer doesn't work. When I'm hovering on the part far from Maczor, it's yellow and when I get close to him it turns red and I can't attach the hook. I would think it should turn green? I'm currently de-orbiting the craft so I can add more solar panels and also try starting with grappling hooks. Am I correct in assuming I should be able to attach the grappling hook to any other craft? Or are there exceptions? Magnetic Clamp needs more power!
