Honestly, the latest updates have just annoyed me. I don't play this mod anymore, since I really can't stand some of the recent changes. :/
You can give out regions, and they'll hate you for it. You can be hated, die, play a new and liked character, and everyone will hate you once you become regent for some reason.. Just because you're new I guess? It doesn't seem to matter that you're a nice guy replacing your tyrant father. If a vassal is humble, he will hate you forever if you're proud and/or ambitious. Having different personalities is fine and everything, but a vassal with 1 region really shouldn't want to go to war because you're ambitious and he isn't. It's just ridiculous. Too many -30 personality differences.
There are plenty of people in this world that I don't like.. Or even dislike. That doesn't mean I want them dead though.. I just tend to avoid spending time with them and everything's fine.
The huge personality difference penalties also makes it nearly impossible to change to elective for example, even though you'd assume they'd prefer elective to primogeniture. You can't have any vassal with a negative opinion, which is pretty much impossible to avoid once you have 10+ vassals.
The only thing I really like about this mod now is the change to Crown Authority and Holy Wars. In Vanilla it's just way too easy to keep HRE etc. happy and functioning no matter what kind of stats your leader has and how horrible you treat your vassals. CK2+ is much better in that aspect, but the recent changes just aren't worth it to me.
Oh, and a small minor thing.. Are children completely random in the latest updates? You can be a genius and only marry geniuses, and you'll end up with tall kids, stuttering kids, hunchbacks, strong kids etc. and hardly ever get a genius from that marriage..?
