SUCCESS! Not only do the unique ships work now, but the unique equipment is spawning now too!
Summary of bugs:
The trade good search parameters do not work properly: Fixed by me.
Unique ship crash: Now fully fixed by me, the ships have their special powers, and the right price.
Unique equipment doesn't spawn: This was infact the SAME bug as the unique ship crash. My fix fixed that too as a side-effect. The unique equipment looks nice, and contains unique hulls too.
For example, in the pirate base I see several new Pigamar series hulls, with increased capacity for carrying missiles.
So, what bugs are left?
