I was not able to choose the second boomtown spot for "straight line bonus" in a 2 player game even though I had the needed metals to take it. Is this something that isn't allowed in a 2 player game or was this a possible bug? FYI this was also the last turn of the game. I don;t know if that changes anything... Gold West n°440953079

if someone else reads this and thinks its a bug and not the rules I will submit to the BUGS forum, thanks!
