Clear out your postmaster. Problem solved. Edit: Also, stop saving exotics. THIS HAS IN THE ENTIRETY OF DESTINY'S HISTORY NEVER BEEN A THING EVER TO HAPPEN TO ANY PLAYER EVER. When you pick up an exotic, it becomes a potential exotic from the CURRENT loot pool. You're not gonna pick an exotic up and open it next month, next season, or next DLC, and ever, EVER, get a new exotic from the loot pool.
