The 200 charm perks morale leader and natural leader are bugged. I haven't explored all the issues but for example morale leader says -1 persuasion for lords of your own culture. I am empire and when I try to persuade empire people I get 4 charm checks needed, but if I switch it to natural leader which are lords of different culture then I get the -1 persuasion, As I said I am not sure how much is bugged but both perks at 200 need to have the code checked.
