Challenge Mode Dungeons Re-open on Wednesday - Updated July 29

#1 - July 24, 2025, 10:35 p.m.

For a few hours following the launch of Mists of Pandaria Classic, Challenge Mode Dungeons were accessible to max-level characters and due to a bug, players incorrectly received Achievements for accomplishments they did not complete. We quickly closed access to Challenge Mode dungeons as soon as the issue appeared, while we worked to diagnose the problem.

We have fixed the issue, and to resolve it and equal the playing field, we’re moving forward with a clean slate and removing all Challenge Mode Achievements that were attained during the period of time that Challenge Modes were open. Further, so that all players will have access to Challenge Modes again at the same time, we will unlock access to Challenge Modes on MoP Classic realms in this region at 03:00 CEST on Wednesday, July 30.

Thank you very much for your feedback. We’re excited to see you dive back into Challenge Modes in MoP Classic.

We’d like to share more about what happened with the Challenge Mode Dungeon system last week, and our plans moving forward.

What happened?

After the launch of Challenge Mode Dungeons, we encountered a few bugs that heavily impacted those who were pursuing realm firsts. To help maintain a fair race, we disabled Challenge Mode until we could get those issues fixed. Those bugs included:

• Players who did Challenge Mode Dungeons were awarded every medal (Gold, Silver, Bronze) regardless of the completion time. This affected a small number of players, but these achievements have unique associated rewards that players would get without earning them. It also had a huge potential impact on the race on each realm.
• Players who completed Heroic Temple of the Jade Serpent were not being rewarded the Heroic achievement, which blocked their access to the Challenge Mode version of that dungeon. This halted groups at 8/9 progress.

Now what?

We fixed the Heroic Temple of the Jade Serpent bug, and players will be able to access that Challenge Mode when they go live tomorrow.

We’ve identified the players who obtained Gold, Silver, and Bronze medals incorrectly and we’re clearing those achievements from players during maintenance. Thereafter, anyone impacted will log in to find those achievements and rewards removed.

We’ve identified the players would would have earned the Realm First! Challenge Conqueror Gold! achievement if the system had not been taken offline, and we’re going to award the Realm First! achievement to them before Challenge Modes are reopened. Again, players will log in and find the achievements awarded.

Our process for determining who would have earned the Realm First! Challenge Conqueror Gold! achievement was quite comprehensive. We took many factors into consideration such as: completion times, acquisition speed of the achievements, players current progress toward Realm First! when the dungeons were disabled, and their lead on the second and third place teams.

In cases where the times were extremely close, we’re awarding it to multiple groups of players.

The removal and addition of achievements will take place during realm maintenance, which is scheduled for 03:00 CEST on July 30.

Thank you so much for your passion for the game, your participation in Challenge Modes, and you patience as we get the system functioning properly!
