It appears that I can’t change my outpost in Gorgrond from lumber mill to sparring arena, making it impossible for me to complete the achievement “Prove Your Strength.”
I believe this is because I first chose the Sparring Arena (years ago) and completed the quest line to unlock it, then switched to the Lumber Mill without completing the achievement. It seems the quest line to unlock the Sparring Arena has stayed flagged as completed, thus I can’t pick it up again. As far as I’m aware, there is no other way to switch back.
The following quests that unlock the sparring arena are currently flagged “true” for me:
- 34697 - A Rediscovered Legend
- 34698 - Slave Hunters
- 35152 - The Sparring Arena
Also: For me, Kash’drakor is located in Beastwatch (46.3, 69.3) not at 42.8, 63.0, also indicating that I have completed “A Rediscovered Legend.”
Others have noted that if the lumber mill followers (Penny and Kaz) are on a mission, you can’t switch back. However, I have ensured they aren’t on missions and I still have this problem.
Fortunately the achievement “Prove Your Strength” is account-wide, but it would be nice to have the option to switch back and not need to complete it on an alt.
