Loot from Hive Colony gone after death

I just got my first breachlord kill in hive colony, but died at the same time as the lords. Last thing I saw was breachlord limbs and some other loot droping, but as i returned to the map the hive was disappearing, ant i could not get the loot neither the special ascendancy tree.
The hive should stay open for cases like that.

BTW, hate that fight, too much bling in purple and white, no good visuals whats happening, don't know what i'm dying to most of the time.

Not certain, but I completed this recently and when I went to exit, it gave me a warning that I could not return. So I think the area may close after leaving once fight is completed.

May have design flaw, sort of like you loose access after fight is complete, which in general is fine, but in case of dyeing after completing the fight has blocked you out.

I agree, if that is what has happened, it is bad, and should not work like that. Should be either 1 entry, or free access while in the map. Maybe there is a technical reason to have it like this, but game play wise it is not good.

If you died on the last map portal, that would be fair enough, but you have effectively been punished for dyeing at the wrong time, when someone could of used more portals than you, but not died exactly at the end of the fight.

Maybe they could do it like in Alva encounter, you get the loot after you get back to the map.
That would leave you with the punishment of not having the new ascendancy, but you got the loot you "earned" b4 dying if you have map Portals left.

I think you should have access to both. You completed the fight and still have portals. They just need to improve it. Unsure if any of the other bloodline bosses work like that. Probably should be a feedback post, because I think it is something they need to change. They have been making changes through the league with the loot drops, I think with the regular hive they changed it to work as you are saying. This is more niche, but probably a bigger problem, since it is higher level difficulty.
