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.
