We have a bit of a dungeon availability switcheroo today, as Blizzard have fixed the Plaguefall issue and turned the dungeon back on, but also disabled Timewalking Court of Stars! 

Dungeons (Source 1, 2)

We’ve identified an issue causing some players to become trapped in the Legion Timewalking Court of Stars dungeon and we’ve temporarily removed the dungeon from the Timewalking dungeon finder. No one likes being stuck in Court.

The Mythic+ version of the dungeon appears to be unaffected by this issue.

We’ll let you know when we’ve got it fixed and opened again.

With a hotfix, we’ve re-enabled the Plaguefall dungeon. The terrain issue some players were experiencing has been fixed.

Thank you.
