Boss not dropping loot after killing boss

After I killed the lord of the pit, i assume the zealous inquisition proct and it insta killed the bone colossus. But no items dropped. It was also on a 186% total rarity increase map too (without gear included) ;_; Those other items I got before the boss. https://imgur.com/a/KXiLAyR https://imgur.com/a/J6KqG4h

Can confirm, same map. when zealous procs on one boss and kills the other no loot drops
