Hello. I've been working on ATT (best addon ever btw ;) , but i got stuck now that i was progressing through Deepholm. I was in this area back in 2010 and completed whatever there was at that time.
So... I have the The Stone Lords achiev, i have the pet : Pebble wich most likely would already be enough to have ATT listing the quest "Pebble" as completed. At moment it's listed as incomplete.
Kor the Immovable also has nothing to offer to me.

Can anyone help me, has it been reported previously? Am i missing anything? :|

It gives me the state : false
I'm pretty sure all i did in deepholm was with the toon shown "Koub". Can only remember beeing there also mining and herbalizing with a hunter, but no idea about his quest progression in the area. Ended up running the script in all characters. They all have the result : state: false.

PS: ty very much for the fast reply. I keep my hope it will be possible and "easy" to fix.
Best regards.

Thanks for the report. If you could in WoW type this in the chatlog:
/script print(IsQuestFlaggedCompleted(28869))

That will return a value from Blizzard stating if you completed the quest or not. Which is where we pull the info from, but possible it could have gotten it wrong.
The other question is did you do it specifically on that toon? You could have the criteria / pet from another toon, but not that one. Which could cause the issue too.

Thanks for letting me know that value.

Since it is returning "false" that means you didn't complete the quest on that particular character. Since it's returning false there's nothing we can do to mark it as complete since that's done by Blizzard's end.

This does pose another question that we (our team) need to look at. We have it listed under that criteria which shows you earning the achievement without needing the quest. So we'll have to quest through there again and see.

A few other questions, what are your quest settings like? Here is a copy of the setting's in-game. The main ones I'm looking at are highlighted in Blue and Green. Also in the same screenshot you can see that it's showing the quest "Pebble" completed for me.

Sorry the delay.
As previously stated, i rolled the string/script on all chars. It gives "false" in all. Can´t be right, im 98% sure i did it on the paladin shown in the post, and if not on him, i'm 100% sure it was on a hunter i use to farm mines and herbs. The script should've give true in one of the chars. I'm considering opening a ticket to Blizzard to clarify that (should I ? :| ).
The pet is not tradeable or marketable, it's listed as obtainable as a quest reward, that lends me to assume i had to forcelly made the quest for him (on any char).

As for the settings; after i altered them to your current ones, it lists the quest and achievmente completed as follows in the images below:

Before i changed, my settings was like this:

After suggested changes settings:

Meanwhile took the liberty to verify as well if the hunter i use to mine/herb had the quest as completed; and it doesn't. It get's stranger and stranger at any attempt to understand:

There is probably too much to worry about at moment, with BFA and all that it probably involves, so i really want to thank your time spent with this and the tweak suggestions and attempts.
TYVM. I hope everyone else appreciates your efforts and dedication. BEST REGARDS!
Koub.

Just want to update:

After trading tickets with blizz support GM i have to rectify that this post in NOT correct.
TSM end is working like a charm.
I DID NOT COMPLETED THE QUEST, exactly as TSM tracks, because it's a skippable/optional/crumble bread that can be done with or without the pet (collected Pebbles).
The pet is a daily quest reward.
Sorry for all the mis-leading information and TYVM for the time spent reading my mistakes.

Best regards TSM team. One day i will be rich, one day i will make up for "you guys" ;)

Koub, the Noob.
