From this week’s TWID:
As we approach the end of Season of the Deep, players should make sure to claim all engrams and other rewards before the new Season begins. Any rewards not claimed from non-Seasonal vendors will be removed at the beginning of the next Season.
Players should ensure that they have collected any earned but unclaimed rewards from their Previous Season Pass page for Season of Defiance.
Previous Season Pass rewards can only be claimed up to one Season after it concludes. Once we transition into Season 22 on August 22, 2023, the Previous Season Pass page will be updated for Season of the Deep rewards.
TL;DR: claim any vendor engrams from the Tower as they’ll be reset on Tuesday. Claim any season pass rewards from Season 20 (Season of Defiance) here.
Someone on Reddit said the same thing, and the replies were that it was a bug and shouldn’t happen this time.
Welp, time to get some legendary
gearshards!
