Boss drops no items/currency, only piles of 1gold each in juiced map

I have had it happen twice this league (Dawn of the Hunt). Just now it happened on a corrupted tier 15 map on atlas it was an irrediated Backwash with boss (no other side content on mapdevice, no delerium on the map)

I was effected by 2 shrine buffs: freezing shrine and diamond shrine. NOT affected by the shrine that converts drops to gold.
Earlier that map I crashed to desktop, maybe that has to do with it. All other monsters drop items like usual (before and after defeating the boss)


The mapboss dropped about 12 piles of 1 gold each.

map mods:
14% increased gold find in area
Area contains 18 additional packs of vaal monsters
61% increased magic monsters
47% quantity of items dropped by Map Bosses
+1 to monster level area
Monsters have 246% increased stun buildup
15% increased packsize
10% increased quantity of items found in this area
101% increased rarity of items found in this area
delirium fog has doubled the difficulty scaling
69% increased waystones found in area
50% increased stack size of simulacrum splinters found from non-unique monsters in area.

The other time it happened this league I thought of it as an unlucky coincident altough I did remember that map was also quite juicy.


I'm using ancestral warrior totem linked with rolling slam (weaponset1) and Rake linked with stomping ground(weapondset2), I have 93% player rarity with those skills, and I have a Golden Charm.
