I declared a formal war against an enemy. I immediately got warmonger penalty of about 40s on all leaders. In that war i cede 2 of his cities and liberate 2 city states which are not my allies. When i captured the cities one by one, my penalty kept adding up until it hit 80s. But it clearly says that liberating city states remove severe penalty, so i did. I checked the penalty immediately, it's still the same. OH maybe it's in the next turn. But it's still the same the next turn. Hmmm i read again, "it will count when the war end whether you decide to keep this city or not" oh okay let's end this war. But no, my penalty doesn't go away and it's exactly the same. Is this buggy or has some mechanics that i don't know?
