Not sure if this is worth bothering sending in a ticket (w/save file) or not, but I thought I should at least mention it here. Decided to give the Iridium a shot today, as they are a completely new race (if similar to the Korx) and I haven't played them in GC III yet. After learning my lesson with the Yor, I decided that maybe I should scope out their tech tree a bit before really starting them.
One thing I noticed is that they get two separate techs that enable the Starbase Market module. Now I know they love money, but this seems a bit much. 
Still, I suppose it could be intentional. But in case it isn't, here are a couple of screenshots showing what I am taking about.
In this screenshot it shows that the tech "Customer Relations" will grant the ability to build a Starbase Market:
However, this screenshot shows that the tech "Marketing" will also grant the ability to build a Starbase Market:
Now this certainly could be intentional. After all, the Iridium really love money, so this might be a way to make sure that the player gets this module early. But it does seem more likely to be a bug, hence my commenting here on it.
As I said, I'm not sure this is worth sending in a save file/creating a ticket over it since it is so basic and easy to spot. But I'll send one in Stardock wants me too.
