I did a search before I posted this, but I didn't see anything like the problem I have.
I bought GalCiv 2 Gold last week and recently updated to the latest version.
I selected the Terran Alliance, and decided to change the name of the leader to my own. I started the game and noticed my neighbor was the Terran Alliance!
I quit and went back to the civ selector, and noticed now the Built in Terran Alliance was no longer the same name as it was before. Everytime I try to play as them there is always two of us.
I figured it mustof created a custom race, so I went to that screen. Now all it shows is the customized Terran alliance. Also, I can't customize it! Can't change the description, can't change the starting techs...
Its not a show stopper no more than it is frustrating. Basically I lost the race customization feature. It really makes me think they didn't test this very well.
