Argentum Fox

Does anyone know why i can't EVA from the Command Module Mk2? (can't exit, module has no hatch). There does not appear to be a visible door.

Increasing the mass does indeed strengthen the joints, but I've tried your suggestion it just cancels out the mass of the part and the wobble returns. I also tried adding "PhysicsSignificance = 1" to the cfg file but that causes the part not to work at all. There must be a way to make the part have high mass but maybe ignore gravity?
