I don't understand how you can have militancy so high, and yet have contentment at 95 and revolt risk at 0.
As for the high militancy figure, I tried passing some reforms, but each time militancy dropped by only 2-3 percent for a couple of turns before going back up to 100.
Meanwhile, when you hover the cursor over the reform button, it only tells you that selecting it will reduce militancy. I would have thought it would have some other effects as well, but nothing else is mentioned.
And what's the point of spending 200 or even 500 on reducing militancy when it only has a tiny effect for a couple of turns?
