Killing Boss in Bone Pits with the Devouring Diadem equipped doesn't drop the Mastadon Tusk

It appears that the Devouring Diadem consuming the necromancer's corpse during the boss fight prevents it from dropping loot, including the Mastadon Tusk needed to continue the campaign quests. This also appears to prevent the boss from spawning the lightning ball that's supposed to appear after it dies.

I did not test with other methods of consuming the necromancer's corpse, but i suspect they may also have the same issue if the corpse is consumed quickly enough.


Additionally, the boss respawns after defeated when the player selects 'respawn at checkpoint' from the escape menu, even when defeated without consuming the corpse and dropping the tusk properly. The seems inconsistent with other bosses.
