This is extremely helpful, thank you.

Since Kerbin's equatorial plane is aligned with the ecliptic plane, how do I determine the origin (zero degrees/reference point) for longitude of ascending node without using mods? I understand that at UT = 0, a ray drawn from Kerbin to Kerbol is nearly aligned with it, but I don't know how to determine it in the map once a game has begun. Thanks y'all.

Howdy! I've had this issue too. In order to reproduce this problem: 1 Create a vehicle with several contiguous joints on one or more limbs 2 place the vehicle on the launchpad 3 traverse several joints. to make the problem more noticeable, be sure to deflect joints more than 30 degrees 4 perform a quick save 5 perform a quick load 6 traverse several joints Prior to loading the save, the joints behave just fine. After loading the save state, the joints do not behave as expected. As Cameroon mentioned, there are several duplicate ship parts which are far off-axis yet still attached to the ship. You may need to zoom out in order to notice this. When deflecting joints now, the original direction may have been reversed, and the extraneous parts collide with terrain and objects as they move around. Many spanks!
