I play AC Valhalla on PS4. I have noticed that, from time to time, there will be what I call a "pop-up quest" which entails avenging a dead player (I believe an NPC Jomsviking). If you have Eivor inspect the body, Eivor will narrate the manner of death, then you will have the option to avenge the dead body for some XP. Anyway, I sometimes use the skill Explosive Corpse, and when an enemy triggers the booby-trap, they are sometimes killed/disintegrated, not just injured. Sometimes, after this occurs, an "Avenge" quest will pop up, and I will accept. I have noticed that sometimes, the green quest sigil appears at the location of a body that has previously been exploded by the afore-mentioned booby-trap, leaving no body to perform a "confirm kill" on. So when this happens, I cannot complete these quests. Anyway, they are side-quests at most, and I can abandon them at any time, but it is a bit annoying, and I was wondering if anyone else has experienced this or brought it to Ubisoft's attention, so I figured I would ask. Thanks!
