What is level races?
 

Maybe was asked before, I missed them, sorry.
This because sometimes races leveled up.. this could have impact to player? Like.. Fringe level 3 have more components to sell ?

They'll have better technology available, and bigger ships to guard their planets and attack other colonies.

I have never seen races level up after my first galaxy.

Same here. It was actually really intriguing to see that happen, figured it might have been a bug since it stopped happening.

it's happening sometims, for now in my most long run (20level ship, fourth sector), I've seen this 3 times
