Esh and Tul boss fight loot bug

Killed Tul and Esh. Was full hp. After they were dead i start waiting for the loot and something insta kills me. So far - so good. The bad part is that I get teleported outside the hive and it disapears with all my loot within. Half of this league is the same trash - you fight - you win - no loot. And by no loot I dont mean bad loot - but any loot.
