Having this same issue. Spent the last 20 minutes running all over the hall using the macro every so often, and it never printed yes. Not sure if there are more requirements than listed, but here's my current progress in the expansion so far:The frost hidden appearance's "quest" doesn't complete for me either.
- Level 110
- Class hall research level 2 unlocked
- Artifact weapon research part 1 completed
- Nightfallen to Honored
- All available Suramar questlines completed
- Class hall campaign is not completed
I'm wondering if the last one is a necessary component or not. My final mission is currently running, so I should finish the campaign tonight or tomorrow at some point. I'll keep testing a bit until then, but I do believe I've covered every inch and crossed every step possible so far without returning a "Yes" result.
Also completed the pre-raid portion of the Balance of Power / The Power Within questline. I'm past the point I was at on the beta, except for the artifact research, and I have the hidden frost appearance on the beta.I just completed my mage class campaign and the quest trigger still isn't working. Hidden daily roll quest remains uncompleted.
This tells me that it's one of four things:
1. It's not activated yet, and the appearance isn't obtainable yet because of that.
2. There's some relation to artifact knowledge level, and I think this is the most likely thing if it's not a bug.
3. There's some other hidden thing that has to be done that someone wouldn't normally do, but someone might accidentally do while out in the world (click an object somewhere? talk to a seemingly-random NPC?)
4. It's just bugged, and the appearance isn't obtainable and won't be obtainable until that's fixed.
It could have changed from beta, but I really doubt it would've changed that much.
