SystemTypes problems
 

I've been seeing a weird problem with entries in the SystemTypes.txt that I'm working with.

I have an entry like this:

Obj 2 Physical Type := Planet
Obj 2 Position := Ring 2
Obj 2 Stellar Abil Type := Normal Planet
Obj 2 Size := Any
Obj 2 Atmosphere := Any
Obj 2 Composition := Rock

It should display a rock planet of random size and atmosphere. But instead it randomly produces Rock, Ice, and Gas Giant planets.

Anyone know what could be causing the problem?
