Here's a bug to fix the next time Invade Earth gets a touch up.

I've noticed that players (computer or humans) can place an army during the start (prologue) of the game. However, according to the old belgum2210 scan (http://web.archive.org/web/*/http://www.belgium2210.be/files/frontline.pdf):

"Players do not start in the neutral territories".

I can't confirm, but I thought that the neutral territories didn't have associated territory cards, as well.
