The Forsaken expansion has implemented a number of changes in Destiny 2, but players have started encountering a number of noticeable issues. After monitoring player response, Bungie has posted a statement detailing how the development team is handling four of Forsaken's larger problems.

Perhaps the largest issue is a result of a faulty milestone reset on September 8. Players who completed any of the weekly Gambit, Crucible, and Heroic Story challenges after this reset are not receiving the correct high-level rewards and will not receive a proper reset on Tuesday. Because Tuesday's reset is the last one before the Raid on Friday, players who encountered this issue may be unable or struggle to become Raid-ready in time.
