The rules state that you count "all Locations built in your empire" but the FAQ says to only count Faction buildings to determine win/loss against the Virtual player.
I understand typos and printing mistakes, but here is a big difference here. How could the rulebook be so wrong?
1) I am not sure which FAQ you reference. I only know of one official one and it does not have any clarifications on the solo game.
2) the rulebook online (all I have access to at the moment) doesn't say "all" as you have quoted. And while it doesn't make a distinction here about Faction only, the opening paragraph under Goal does state Faction Locations. So while it should have been clearer here, it isn't necessarily contradictory to the opening rules.
Maybe the printed version is different than what they have up now.
