The Hall of Statues in the Vale of Eternal Blossoms is bugged. In the old version of the Vale, the floor loads both versions, making every tile have two effects. This makes the achievement (One Step at a Time) impossible since there’s no safe tiles, and makes the quest very aggravating since there are now wind tiles in front of the orb you need to click, which push you back from the orb.Its only for 1 part of this achievementcalled : The Crumbling Hall QUEST. Second quest work perfect.

I understand where you are going from with that feedback.World of Warcraft is an evergrowing game, with hundreds of thousands quests, locations, NPCs, many complex mechanics etc. All of that is managed by a limited number of people who can actually do changes within the game.
While we do appreciate that players would want to come back to old content to pick up old achievements, quests, transmogs etc, sometimes the focus needs to be placed on more pressing matters (fixing emerging bugs in new content or… preparing new one)
As long as the bug was reported and verified internally, it will be fixed eventually. Just please keep in mind, that reporting them through tickets would not be as impactful as reporting them through specially designed channels (bug report system in game).
We in here have no capacity or access to the game mechanics, we are administrating your account. Not the game itself.
Bug reports from game and forums are sent directly to developer’s team, and while there is no promise they will receive a reply, those are red and lodged for our quality assurance team to investigate.
So again, thank you for sending bug reports via appropriate channels and for your patience.
Best regards,
GM Lourithea
