I have been leveling Heavy Armor and decided to finally start making sets. I built a 5 armor pieces of Whitestrake's armor and then the remaining 2 pieces in Night Silence. All the set bonuses lit up.
I then built a Night Silence sword -> no new set bonus. Confused, I went and build a Night Silence Shield and Night Silence Bow. So now I have the following pieces of armor/weapons in Night Silence:
Waist
Shoulders
Sword
Shield
Bow
So that is 5 traits, but the screens only show 3 of the 5 actually being active. Why is that?
