If you have been playing legendary lost sectors and ran out of respawn, one would try to leave the activity and tweak build, and interact with the banner again. Except you can't. You cannot leave the activity, or teleport, or anything for that matter. You can only stare at your ghost as the game infinitely loops "Finding spawn location" even though it knows you have no revives left. The only thing you can do is switch character or close the game. This will put you into orbit again, if the legendary lost sector is far away from any TP point then that makes this whole ordeal much more breathtaking.
