Lost Jeb last night when he was shot from the capsule at about 3 m/s..... after already landing on the Mun :-/. Suffice to say the impact liquidized him...
I wondered the same, and gave the can and 3 man lander a shot. At first it seemed to be ok, but after several in and outs, they just floated off. It certainly happened less on the larger pods, but its still present.
