Many players are currently having an issue with starting the fourth Spark quest on live servers and here’s a potential fix for the problem.
What’s causing the issue?
Players who completed the second challenge took the Bottled Essence but forgot to pick up the follow-up quest Well Earned Victory. As a result, the subsequent quests are not showing up for them.
How to fix it?
Run the following macro by Reddit user Jedi_2113 to ensure you’re missing the third spark quest:
/run print(C_QuestLog.IsQuestFlaggedCompleted(70341))
When the returned value is false, you must head back to the second challenge location in Ohn’ahran Plains (66 55) to pick up the follow-up quest from Maiden of Inspiration.
