Not sure if this is a bug or not.
Played a match where I maxed out objective and when I viewed my over all score, I was rewarded silver in lightbringer. I did co-op on the generators with prove thyself, opened a chest and opened an exit gate to 99%. Also I didn't take a hit from the killer at all and only got into a chase at the end but didn't get any emblem in evader. I also sabotage two hooks for extra bloodpoints.
So is this a bug or is it normal emblem system?
