I'm using Jefferson's KAS fix for 64bit and I've got a bug. Everything worked well enough on the ground, but in orbit around the Mun, when a Kerbal grabs a Pipe End Point off the ship (only part tested) that Kerbal's relative velocity immediately becomes zero. The ship disappears over the horizon, carrying on its orbit, leaving Jeb (and later Bill) to die horribly; slowly falling straight down (more or less) at the surface of the Mun. Am I alone with this bug? My next test is to put them on ladders and see if that makes a difference. We've got to save these Kerbals! Update: Tested in 32bit. Working fine.
