There are two SSO quests relating to a vendor on IQD sending you back to Shattrath to speak with the portal daily questgiver when unlocked. If you bypass this quest and and speak to Nasuun / start the portal daily, it appears these quests are flagged as completed and/or disappear from the tradesman.

Questie does not flag them as completed/remove them from the Shattrath quest list when this happens.

Questie - v6.12.3

Please also state if your quest issue is about Classic Era/SoM or TBC.
TBC

It should be shown as unobtainable at that point. - after fixing. No idea if anything has done to this yet.

We need to find out if the two "Report to Nasuun" quests (11517/11534) become available again when the daily resets. If they don't this needs a database format change, because when the daily resets we would show the quests as available again because the API says it's unfinished.

Closing this in favor of #4012
