I'm not sure that I would necessarily classify this as a game bug but I noticed that when I downloaded and installed the game via stardock, the shortcut created on my desktop was for GalCiv2:DL and not for DA. Being new to the game I didn't really think twice about it and assumed that since the gold edition bundled the original game and expo pack together that they only had one .exe. It wasn't until I started playing a few games and reading up on the forums that I noticed inconsistencies between my gameplay and what I had been reading on the forums (i.e. gameplay things missing etc.). So I went into my GalCiv directory on my hard drive and saw that their was an .exe for DA. Problem solved however I think it would have been nice if the download/install process via stardock either created both shortcuts to avoid confusion.
