QoL - Hive Colony

I completed a hive colony and took down It that was Tul/It that was Esh with a friend a few minutes ago. I died at the end of the fight and I stayed down until the bosses were defeated, however... when I went to revive and go back in to grab the Breachlords body part there was nothing there for me because the hive colony evaporated when I got close to its entrance again in the map.... The Hivebrain Gland or the colony needs to have its own portals or at least be accessible after its destruction if a player is still inside like my friend was.
