I've just checked Impulse myself(waiting for entrenchment update which is about to be released) and I've noticed the same thing. I still have all the latest updates though. When you run your game check the little number down in left hand corner (on the sceen that gives you single player, multi player,download updates etc.). If it says 1.13 or entrenchment 2.5, if thats what you've been updating, then your game is up to date.
Hope this helps, also 1.14 is about to be released + 3.0 entrenchment.
