My progress on a lot of achievements got reset with the prepatch.
Even ignoring the achievement progress and still completing the parts I still had to do (just did 6th week of All Sides of the Story / treasures) doesn’t grant the achievement, so it is not just a visual bug.
The achievement I could find that got reset are:
Just One More Thing
To all the Squirrels I love Despite Their Scars (not 100% sure)
Treasures of the Ohn’Ahran Plains
Treasures of the Azure Span
Treasures of Thaldraszus
All Sides of the Story
Fisherfriends of the Isles
The Seat of Knowledge (not 100% sure)
History of the Mantid (not 100% sure)
Secret Fishing Spots
Best in Slot
Tetrachromancer
The Disgruntled Hunter (not 100% sure)
Full Discography
I tried resolving this with a ticket but I basicly got told to go to WoWhead.
After reopening the ticket I got told to complain here and my issue got marked as “resolved.”
Still waiting for a fix…
