I have played several games and I have yet to see any planetary improvements actually "work". For example, if I have a colony and I find a "Fertie Soil" tile (increase the food production of any project on that title by 200%) and then I build a "baisc farm" on that tile aren't I supposed to get a food production of 8 on that title instead of the standard 4? The problem is that I just get the regular 4 on that tile (so my colony grows from 5b to 9b, but no higher) ... I have played like 10 games and have never seen these improvements, any improvements at all, actually work.
Am I missing something here? Are the bonuses listed somewhere else or something? How are these improvements supposed to work? Thanks for any feedback on this as I'm going a little crazy here!
