We've ran a few rounds as a group thru Underweave, and these two bosses just didn't drop any loot for anyone, ever, much like Malabal Tor bosses were (are? I think one of them is still) bugged.
(PC/NA)
I spent a hour or so in Underweave today and Caz and Silent bosses were not dropping as soon as they died they turned white with no loot drop. I thought it may be my companion so I tried without it and it was still the same. Creep boss only was loot-able a few times, again like the others turned white with no loot drop.
I killed the group boss 5 times and only once did it drop loot.
I was finding the same thing - that All-seeing Kyzuu didn't drop loot. It think it must be a timer between boss deaths.
This timer is ridiculous! The bosses in this dungeon are close together! What lore reason is there that they cannot drop loot close together in time? I could understand if killing the same boss too soon didn't drop loot. But killing different bosses should all drop loot.
Are you waiting at least 5 minutes between boss deaths?
They don't drop any loot at all. The corpse isn't highlighted. That's the same whether it's the first thing you kill in the PD or you've killed other bosses along the way. Usually, if you kill a boss too soon you'll still get some gold to loot, but these bosses drop zero. It's happened to me/my group since Necrom launched on console.
Creepclaw and All-Seeing Ky’zuu was working for me on PS NA, I have been farming Creepclaw for the lead. There was another boss that did not drop any loot for me, though.
I think it was Loremaster Trigon.
Just like the post above, there was no loot. The corpse disappeared.

If the kill is under the timer, the bosses still drop some small amount of gold, just not other loot. These don't drop any, whatsoever, regardless of timer. Even waiting at the group event for the boss to respawn several times did nothing.
