Insufficient Intel on Enemy units at all times? bug?

[Sensualc4]

So up until I stumbled into world war II.. I could see the unit type, #, manpower and organization of enemy units in adjacent provinces. Now all enemy armies say insufficient intel even when they are attacking.

I wasn't able to fine a thread about this, is this a glitch or is there a piece of tech I need to research? Thank you!

one of the industrial tabs (one's actually industrial, i forget the other) has a line which starts with one tech i forget the name of, the splits in two. the right hand branch is computing machines. each of Those techs has a tech to each side of it. one of them is decryption, the other is encryption. if the other guy has more encryption than you have decryption, you'll get the issue you're having, as i understand it.

though other factors may be involved too, that's the basic one.

(essentially, you can't crack their codes so you have no idea what's going on in any of the bits where your individual troopers don't actually have eyes on the enemy... which, on a "a division is one manouver/combat element" scale, is... umm... not a very useful amount of information. that's the part that lifts the fog of war enough to know that there are enemies there at all, admittedly, but that's it.)
