I am playing on a custom made tiny map with 8 planets. Each faction controls 4 at start. All the planets are level 26. I've started the game a few dozen times, but I still can't get precursor mines or libraries (the +700% bonuses) on any of my faction's planets. Is a certain map size/# of factions required for these bonuses?
Note: I have seen all the +100% and +300% bonuses on my planets.
