[2021] @A_dmg04: "Any weekly bounties in player inventory, even if completed, will be removed at the start of Season 13."

Haven't seen this pop up on the trending subjects yet - if you've been bounty hoarding like me, pop those weeklies or lose them before next season.

Per DMG on Twitter- Q: "Do I need to redeem weekly bounties from Strikes/Crucible/Gambit/Gunsmith as they're being removed next season?"

A: Yes. Any weekly bounties in player inventory, even if completed, will be removed at the start of Season 13.

EDIT: Extra info from the TWAB: "...we are removing weekly bounties from the three ritual vendors (Zavala, Shaxx, and Drifter), Banshee-44, and the Seasonal vendor. These vendors will still have daily bounties which reward XP, and the three ritual vendors will still have repeatable bounties for those of you who want to pursue additional XP and Bright Dust."
