Just had it happen to me! Arg! First I was trying to link two ships to refuel my lander. It didn't have any attachment ports so I brought an extra from the refueling ship. Each time I tried to attach one it sent the lander way up into the air like we suddenly lost gravity. Then when I took the fueling ship back I went to plug it back into my refinery and it exploded! AHHHHHHHH!!!!!
