Yah, I tested it out by making a facility that used all the modifiers and built several of it on the same planet. Intelligence and Research is definitely being increased for each, while Construction rate and all the Resource Gens are only being increased by the first one( unless a facility with higher % modifier is built, of course, at which point it uses that one instead ).

I assume the Research/Intel modifiers are the broken ones and not the Resource/Construction modifiers, since the facilities are obviously only supposed to be 'one per system/planet'.

Perhaps a big improvement would be to have the current modifiers( with research/intel fixed ) and in addition a set of stackable ones, to open up possibilities for modders.
