Sorry for my English, i'm from Russia.
How i can unlock the "passive slaughter" hidden quest in Braggin Rights quest line? That quest has a leather icon (I've seen a screenshot). After reading this thread, I realized that I needed to complete the quest at "for the hoarding" quest line, and kill 100 passive mobs. Now "For the Hoarding" is completed at 100% and i killed tonns of passive mobs (over 1000, sheeps, cows, squeeds etc.), but quest "passive slaughter" not unlocked and not visible. I'm doing something wrong or is this a bug?
