So me and a few friends have been running the new exotic mission. We are now past "Soulfeds" Boss multiple times and [spoiler]once we realized we use the symbols on our gun it was too late[/spoiler], we left the instance to grab food. Ever since then we cant launch the mission as an instance that actually allows us to proceed past each submission. Everytime we kill each submissions boss i.e Bloodline or the three bosses in Soulfed it just says "Mission Complete" and once the timer runs out it kicks us. This goes for both the map Door/Flag launch variant as well as the selectable node on the destination. Is this intentional cause we used to be able to progress but ever since launching back in we cant get into a different submission.
