Woodland boss drops no loot (2 bosses)

I think the system has error where it checks if bosses are dead.
If you kill them at the same time(within 1 second) you dont get any loot from neither of them.
If you kill the bosses 1 by 1 or with delay between both kills you do get drops.

How to fix- take the code from sulphuric caverns there the code actually works.

Happened to me 6 times so far.

Happened to me as well (multiple times).
