MANSION IN THE MISTS/ ATALUI BUG

The bosses dont drop anything.
Both ATALUI and MANSION IN THE MISTS.
i've seen another thread saying the same thing about the mansion while trying to farm the lineage gem, that the boss literally drops nothing 0 items shown even after being hovered with alt.
the same bug has happened to me in the map(waystone) which has the act 2 The bone pits zone bosees.
Ekbab, Ancient Steed...

So basically i think there is an interaction bugged with my skill or the way i do dmg with the map having 2 bosses. Cause when i kill one of them eventhough the other one still has a visible amount of hp left it instantly dies as well, and then it drops nothing.

Im currently playing a poison type build with thrasing vines/entangle on pathfinder and my main source of dmg is poison(damage over time).

I had to literally wait for one of my friends to come online and let him do the boss so it would drop any loot.

PLEASE FIX THIS !!
TY!
