Destiny 2’s latest Trial of the Nine player-versus-player event was changed at the last minute after Bungie discovered a glitch that allowed players to leave the map area.
Due to a bug where players can escape the environment on Altar of Flame, we’ve changed this week’s Trials to Countdown on Eternity.

Originally, Altar of Flame was to have been the trial, but players on that map discovered how to glitch outside of it and shoot through its walls at those still inside. Countdown on Eternity is the new map while Altar of Flame is repaired.
Trials of the Nine run on weekends and are Destiny 2’s version of the Trials of Osiris from the first Destiny. Trials of the Nine are 4-on-4 competitions that run from Friday to Monday. Polygon has more details about Trials of the Nine here.
No word yet on when Altar of Flame joins the trials rotation for Destiny 2.
