I'm not sure what happened between yesterday and today but now when I play a Terminus, Abyss, or Ruins raid (for the achievements and testing), as soon as the first timed mutation rolls in, it says "Mission Won". I haven't captured a single point and in one game I didn't even move my guys. It's a nice bug for free easy money but a crappy bug for hunting these remaining achievements.

I verified integrity of Steam files and restarted my computer twice as well as the game.
