citadel

Why am I not allowed to get back into the map from boss room after killing the boss?
The map still has breach and rituals and what not, I wanna complete them but I figured I wanna kill the boss first to get the fragment.

There is no portal that allows me to leave the boss room.... and it sucks.

E: I am talking about the one with jamanra specifically. Maybe it's cause he knocks off a part and we all go downstairs. But you could still add a portal there, so players can get back to the map...
