Hi,
When I add a second star and make the Sun a binary, a very annoying issue appears: as the planet orbits the 2 stars it changes the Orbital parent and that info is being updated on the property panel of the planet. The "Orbital Parent" string keeps appearing and disappearing which causes the other fields to move 1 line up and down and it looks like it is flickering.
edit: sorry for the large image. Just scroll to the right to see the issue.
