yes, you can go into tedit and change that at anytime. if the game is open and being actively played for a while, then it might screw some stuff up, but, give it a whirl
also, just an FYI
the fighter colonist formula
its you get X fighters for every Y product made.
so lets say you have 10k colos in ore making 10k ore a day. you produce 2-1 figs, so you make 5k figs a day.
now you change it is 2-1 ore as well. so those 1k colos only make 5k ore a day, and now you only make 2500 figs a day.
if you have no production or no colonists, it will show N/A as fig production (except in tedit where it will show the correct values)
i hope that helped
