[BUG] Adding Rings problem

[jjwindle]

If you're in a sim, and you try to add a ring with the sim speed at about 20days per second, the rings will instantly expand.
   
                Reproduction:
                1. open a sim
                2. add a planet (tested w/ jupiter)
                3. speed up sim speed to about 20days per second
                4. add rings to the planet
                5. watch the rings expand to the size of a galaxy
                                                                                                                                Please fix this ,
                                                                                                                                         jjwindle

[Plutonium]

Doesn't seem to be a bug. It happens when the radius of the ring is too small and the particles move crazy fast, but when the radius is large and the particles move slower they behave as expected.
