Destiny 2's toughest multiplayer challenge, the Trials of Osiris, has been disabled for more than a month. Bungie says it has found the issue that led it to cancel Trials soon after the release of the Beyond Light expansion, and we now have a date for when we can expect Trials to return: December 18.

Bungie released the date on Twitter alongside its This Week at Bungie blog post. The fix for the issue is coming in a future update--but since Bungie didn't identify it as part of a hotfix coming to the game on December 8, we can probably expect the patch with the weekly reset on December 15.

Trials of Osiris is the peak player-vs.-player challenge that Destiny 2 offers, with loot rewards to match. Available only on weekends, it requires players in teams of three to take on other teams in a series of elimination matches. The goal is to win seven matches in a row without losing any, which is known as "flawless." Starting with Beyond Light, teams that can manage a flawless Trials run can win special Adept weapons, which offer stat boosts that aren't available anywhere else in the game.
