Dream Sanctuary (t17 Valdo map) not giving reward

Abyss was complete.
Breaches were complete, with each breach-lord being killed.
Map bosses were killed.

Reference number: 3,425,835,764

Was supposed to drop voidforge, what gives?!

my only explanation is that somehow a second breachlord spawned in one of the breaches (idk if this can even happen)
