I'm a bit puzzled about how 'sway government' missions are suppose to work.
In my current game, the traders have been running sway government missions in North America every month for the entire game.
I always thought this was a bug that was impossible to fix, because every game I've played, I've had it happen. As of today in my latest campaign, the Academy has been throwing those missions down on Europe every month for something like three or four years. It was cool when I needed stuff from them, but now I sorta... don't. It also led to a near-loss because they kept throwing bases down in and around Europe until I finally got Family Ties.
I mean, at least I unlocked voodoo fairly early due to it. In two of my other games though, I got Mercenaries and Traders, and the Mercenaries were near-impossible to fight at the time.
