I joined a Rhulk Indomitable with some friends as a hunter to start with and swapped to my warlock for another well during Caretaker, then to a titan for thundercrash during Atraks. I then realized after we reached Oryx that I did not have the quest on my warlock, despite being able to join my in progress team without it, rendering my progress in both Caretaker and Planets wasted. I am unsure if I will be able to run it a 2nd time once we clear Rhulk due to not having a team that can consistently play so I'm hoping something can be done to retroactively apply progress to those affected as I know I can't be the only one in this situation.
