Yes, I understand that but it doesn't make any sense to me that one of my other characters picked up 2 fragments that my Warlock hasnt. I've done every tier and every enemy configuration for Tier 1 and tier 2 runes, and have scoured the entire Dreadnought on my Warlock. My other characters should not have picked up 2 fragments that my Warlock doesn't have. I cannot find the fragments anywhere at all.
