Re: Transports.... No more tiny Planets
 

You would also have to alter the Planet Shaper/Planet Destroyer components. They can affect planets up to a certain size, so removing the Tiny planets will require lowering their ability value by one (otherwise, the highest Planet Destroyer would be able to destroy Ringworlds, and it might even be possible to create Ringworlds with a Planet Shaper).

Easier to just replace the values of the Tiny planet entry with those of the small planet entry, other than fields such as Name and Stellar Size.
