Ok so I tried your suggestions, when using Kerbin-Moon-Sun in the template the barycenter works great and the earth "wobbles". Additionally after doing a clean install the additional moons of pluto appeared around Pluto with the pluto-charon-sun barycenter enabled. There are however, some issues. I don't know if they stem from SigmaBinary, from Kopernicus or just the limitations of KSP but I thought I'd report back on whats going on. 1) At the main menu Earth is no longer visible, its just the skybox (I believe this is just a camera issue, it is now looking at the EarthMoon barycenter and not at the planet itself.) 2) There is no longer a day night cycle over the KSC, if I time warp the sun will just hang in the sky. The "warp to next morning" functions normally but does not change the position of the sun. However, if I time warp in the tracking station view to a different time of day, that change is reflected when I go back to the KSC. For example, start a game, its night time, time warp to next morning, no change, still looks like midnight. Go to tracking station view, and the day/night terminator has just passed florida, go back to KSC and when it re-renders everything it is now morning. Timewarp some more, but the sun doesn't move. 3) When I go to the launchpad, I am greeted by a black screen (gui is still present) and it says I'm going NaN m/s (Altitude still 104m), when I try to revert launch back to the launchpad, the game crashes entirely. 4) The orbits of the smaller body in the barycenter still orbits the larger body rather than the barycenter, causing their orbit to "wobble" with the larger one. The moons that I added to pluto do the same as well, orbiting pluto rather than the barycenter. I don't know if this is whats supposed to happen because of limitations with KSP or something is bugging out. 5) When I try to Hyper Edit a craft around pluto or one of its moons, even at very small or large distances the screen goes black and I have a speed of NaN m/s, or occasionally the game crashes entirely. I'm using SigmaBinary 1.1.1, RSS 10.2, Kopernicus 0.4 on x64 Linux if that matters at all. Thanks for any suggestions or feedback you have, I hope mine is useful in some way.
