Boss loot disappeared on death

Location: Mud Burrow
Quest: Treacherous Ground

Both The Devourer and I died at the same time. Boss dropped his loot but as soon as I respawned at checkpoint all loot was gone.

Maybe it is a punishment because I died? Is this intentional?

Edit1: I believe I was killed by a poison status effect from his attack, not sure if that's relevant.

Same thing happened with Secrets in the Dark quest. Died at same time as the boss, all the drops are gone and the quest didn't complete because I didn't pick up the item. The obelisk can no longer be selected to try again.

Same with the act 1 boss, killed them and then died to bleed and lost all loot
;_;

Same for me - lost it all

Same happened to me as well Final boss Act I. Died same time, spawned at checkpoint, all loot was gone.

When I died, I watched to full commentary and saw the loot drop before releasing.

Same thing happened to me - cannot progress

Yo same happend to me at the rust king - died together with boss, loot dropped visibly but as respawned all loot was gone and cant progress. How did such an emerging bug even make it through all the closed beta tests ? *curious ^^

If you die you will lose the loot. That's intended. Just like dying anywhere else in a map, but it isn't intended to block progression.
