ACT 4 ''The Search'' Final part BUG

Basically I was doin the last part of the the search chain quest. The last part consists in killing the bird boss and talk to the hooded one. THe thing is, I killed it and died at the same time, the hooded one appered than disappered cause of my death, and I cant make it apper again. I already killed it two more times, the marker show on the minimap, but he never shows. Tried reseting the map, tried loggin off, but nothing works. https://imgur.com/a/9lAzLLI
