None - hard for me to reproduce.
What you were expecting to happen, and what actually happened
I started a raid battle with Archer class hero in front. Front enemy troop was Valraven and I killed it on first skull match - so Archer class trait kicked in. There was a falling coins animation, if it matters. I killed the boss, but lost the fight. At the end of the fight I expected to get the extra raid sigils from Valraven, but got none (damage done to boss still counted).
How often does this happen? When did it begin happening?
Happened today, on first Bullseye Valraven kill. Haven’t played more raid battles since.
Steps to make it happen again
Start a raid battle with Archer hero vs Valraven and make it die to Bullseye.
