I built a massive lander for the moon which was attacked by a kraken while landing. While landing, I deployed the bottom stage (14 Jumbo-64s and 7 mainsails) to eject the lander (2 X200-32s, mainsail, hitchiker, Mk1-3pod, and landing gear).
What I expected was that the stage would disconnect and the lander would fire the mainsail and land some distance away. What happened was that the lander sank rapidly into the bottom stage, and when it was almost all the way in it registered that there was a collision. My kerbal in the hitchiker went splat and the two in the command pod got launched at half the speed of light out into the outer void. Is there a known solution to this bug? I really want to land on the Mun with this lander, but if I have to eject the bottom stage early, I won't have enough fuel on reentry.
