Hello,
it's mostly that discipline skill missing. if you bump up that stat on races they will retaliate against any violence though this pretty much kills your chances of getting away with crimes and not having no way to retire in any site, though it would take alot to make you an enemy of the state but mostly people would just think you're a killer, and pushing for power of the area and not just trying to ransack the whole place.
No, I'm not talking about the passive stance of creatures which I attack.
I'm talking about the passive stance of bystanders and - more important - every other person of the same entity/civilization of the victim who didn't see the attack. Or, in other words: In Legends Mode you will never see a "The Blarrgh of Glarrgh (enemy)" in your related entity-list. Thus preventing being attacked by the civ you just decimated.
It's the same as the problem with accusing someone as a vampire.
Try it for yourself:
1. Accuse a vampire of being a night creature.
2. Write down his name or slaughter him (the latter makes things easier).
3. Give in to starvation or retire.
4. Open Legend Mode.
5. Search for the vampir (either by searching his name or looking into your kill list).
6. Look who accused him of being a vampire (hint: It's not you).
7. Search for the name of said person.
8. Scratch your head in finding a clue how a long dead person could accuse said vampir.
This bug - and in this case I'm pretty sure it's one - prevents the vampir from attacking you thus leading to being a murderer if you slay him (you have to attack him otherwise he will only spit at you while being nice and friendly in your conversation).
At first I had hope that the person who accused the vampir (yeah, actually it was you but I'm referring to Legend Mode) also would get the enemy-trait in the entity of the vampir. Sadly it's not the case. Maybe another long dead person becomes enemy? Who knows. And for this problem I really would like to see any solution. Otherwise it's boring in hunting humans/dwarfs/elves/goblins/kobolds as this would be a perfect way to start site-wars and FUN in the whole world.
And the sad part is: In older version there wasn't this problem but there was no site-claiming stuff.
I guess you can't have all...
