Bungie has released a list of issues & bugs that will be accompanied with upcoming Destiny 2 : Season of the Dawn update which is arriving on December 10. Mentioned below are the complete list of known bugs & issues
1) Some players may encounter a ‘CHICKEN’ error when logging in for the first time after Update 2.7.0. Players experiencing this error should relaunch the game.
2) Players must have linked an Obelisk to the Sundial to receive rewards at the end of the activity.
3) Season of the Undying seasonal currency is not deleted from the Postmaster when the season ends. Players can manually delete this seasonal currency.
4) The seal for the “Savior” title incorrectly lists a requirement of 28 triumphs completed to unlock. The seal will unlock after completing the 15 triumphs listed in the seal contents.
5) When standing in front of the Obelisk, players can be killed by enemies.
6) Progress may not count towards the “A Matter of Time” quest step if players return to orbit too quickly after completing the Sundial activity.
7) The shields of Barrier Champions will not disappear if a player is using Divinity.
8) These Season 9 Triumphs will be fixed in a future update and requirements will be lowered:
?”Challenges” won’t progress with weekly challenge completion
?”Rituals” won’t progress with weekly Gambit bounties or Infamy ranks
?”Engagement” won’t progress with banked motes
