I am sure it was my stolen rune who summoned the boss fight of Tier 2, Court of Oryx, Bracus Horu'usk, Mengoor & Cra'adug. No one else was around the summon spot and I had my stolen rune used up. The bosses were killed I received blue engrams and reputation but no calcified fragment. I have used up 10+ stolen runes trying to get this boss fight again(its random). My only option now is to grind out black wax idol, and pray my stolen rune summons the correct bosses again and that I get credit for it. If not I will have to wait for 2 resets of Tier 3 court of Oryx, or hope the Nightfall drops calcified fragment soon. I would appreciate if this could be fixed or if I could get an answer.
