Hi there, Thanks for reaching out. The Corridors of Time were closed on 1/28/2020. You can now acquire the Bastion exotic quest from Saint-14 at the Tower. [quote] To access the Bastion quest, players need to save Saint-14 and complete the “Recovering the Past”, “An Impossible Task”, and “Completing an Impossible Task” quests then claim the “Saintly Savior” Triumph. You can then claim the “Memento” quest from Saint-14 in the Tower. [/quote] Make sure that you have earned the associated Season 9 triumph for saving Saint-14 to ensure that you have successfully completed all prior quests. Please also check your quests inventory for any seasonal quests you may have already acquired but not completed. If you have completed all previous quests to rescue Saint-14 and still are unable to acquire the quest try clearing your console/ download cache, you can find steps to do so based on your platform below.
