bug with astetroid

[Cannon]

first i captured it with grabbing unit and it's in orbit around kerbin now, but now i'm trying to grab it again and i just can't, i touch him with my grabbing unit but nothing happens.

before that i destroyed the ship that was attached to it in tracking station.

can someone help?

Hmm, I've never terminated a ship attached to an asteroid before (can't imagine why you would without undocking it first) so have no idea if that caused a problem or not. It wouldn't surprise me if that buggered it, though, because the asteroid is more like a part/ship than a heavenly body, and the claw docks with it. I'm surprised the asteroid even survived the termination of the ship.

If you made a save prior to terminating the ship, try going back to that and NOT terminating the attached ship before you undock it.

Otherwise, all I can offer are the usual things to check. Such as, making sure the 2nd ship's claw is armed and that the surface of the asteroid isn't at too great an angle to the claw. It seems like the claw will only grab if it's at no more than about a 30^ angle to the local asteroid surface. Only a small spot in the center of the claw actually grabs and the extended arms can keep this from touching the surface if the angle is too great.
