i am also experiencing this bug, seems to be any time i add more than one air intake, or use any b9 aero pack intakes. its like the 'parent' part gets dissassociated somehow, because if i put on one 'buggy' intake and try launch, i get this weird bug where my craft appears inside kerbin and burning or something. if i place two buggy intakes then the vab bugs out and i cant do anything but press new. if i try reload the now buggy craft file, then its called unnamed vessel or something. and i cant interact with it at all. i think the bug may be being caused by duplicate parts from both mods, intersteller and some other mod? any ideas? sorry i didnt follow the how to get support thing, but its late and im off soon.
