Map not completing after dying

Hey there,
I came across what I asume is a bug today. I was doing this tier 3 map (entered endgame for the first time not too long ago) and I can't complete the map anymore after dying to the boss once.

TL;DR Objective of map changed into something I've already done before after I died to the map boss. Making it impossible to complete the map.

steps to reproduce (what I experienced at least. No clue if it'll produce the same thing so I'm just going to put the exact situation down below):

1. Play hive tier 3
2. (don't know if it randomizes, haven't played endgame at all before this) Have the boss be The Fungus Behemoth.
3. Map objective is kill the boss.
3. Completed abyss event on map.
4. Go to boss and die (get the notification)
5. After respawn, the map objective changed. And since the penalty causes all other encounters and mobs to be removed I can't complete the map anymore.

Would be appreciated if anybody could tell me if they've experienced the same or if this is just how to game is suppsoed to be.

Its a issue many of us have reported, as far as i can tell GGG has not yet acknowledged it.

If doing a map that requires an event for a questline i suggest doing it on a super low level map because you will brick the entire quest if you fail the wrong node.

In my case it was on a questline yeah, but it allowed me to use another waystone. So it's not really a brick and more of a time waste for me, but I don't know if I just got lucky with that.

Hopefully when more people experience -> report this it will be acknowledged/resolved.
