Despite doing my x5 Timewalking dungeons last week and the week before the achievement for Turbulent Timeways III is only tracking 1/5.
During the first week I did it the achievement it was showing 1/5 but after reset it went down to 0/5. Last week I redid those x5 and got it back to 1/5. Filed a ticket but the rep claimed I didn’t do my weekly time walking “quest” right.
I know there is an issue as I have even saw people with the Pirate Dragon mount last week and it wasn’t even possible getting it then as enough time hadn’t passed. I’ve actually asked in Trade Chat to players to link their achievement and have several names of players confirming it. There are a number of threads on Reddit and Wowhead of people trying to bug the achievement but I really didn’t want to risk a ban. This doesn’t seem to be an issue only localized to me.
My Adventure Journal also confirms I did the x5 dungeons each week on the same character with specific dates. I also even checked my item restoration history to confirm I vendored items that I received from those dungeons as I didn’t need them confirming I did those specific dungeons. I also until yesterday hadn’t run any heroic raids for over a month yet I received the Heroic random raid quest item from the bag rewarded from the weekly TW quest. Further confirming I did do the dungeons.
