Out of interest, what CAN'T you do while stationary?
I have the game paused right now and I went back into it after reading your post, and the only thing that doesn't happen is animation of movement (planet animation ring continues) and of course the flow of messages and any combat. As far as not being able to do anything? I'm able to manage everything and make all decisions as long as they don't require any interaction from other races.
If I find anything that I missed I will surely post here immediately. [X(]
