Star replacement reset bug

Replacing a star in a solar system (with a different star, replacing with the same star causes different bug) causes a few major bugs:
1. Reset of all planet's rotations to the template they were produced from (picture 2 shows the planet's rotation is 14 hrs which is the template rotation speed, it should be 18.65hrs as was set before by me).
2. Deletes the surfaces of the moons of all planets (reset upon reload of system)
3. Resets orbit colours to random base colours (Upon reloading the system)
Not really game breaking but very inconvenient for large systems, which could explain the bug (80 objects)
