Thanks Stardock for the expansion.  Looks good and quite polished.  I did find some little issues that may be easy to fix in a patch.

One of these is that when you buy a planetary improvement, the next turn update seems to always advise you that your planet is now idle, no matter that there are items in the queue, and which the game correctly identifies as next to do.  The gameplay works, but it generates an incorrect advisory note.

As well, I get diplomatic messages whose text needs editing.  For instance the mean Drengin told me something like "Hello, we finally meet Greetings $user name in this galaxy..."
