Hello,
Love your addon.
Since the new patch was released, your addon gives an error in GetQuestTagInfo(questID) in the Blizzard FrameXML\QuestUtils, in functions in Scorpio, line 72 and 67.
I have only Eska Tracker enabled, and error will happen when I click icons on the map, or when quests are accepted, or quests are completed, but not turned in, and can also pop up the error when quest is turned in.

Fixed in the version 1.1.12 of EskaTracker : Objectives. Thanks for having reported it,
