Splintered Spark of Shadowflame not dropping

I have the “power unified” quest unlocked but the splintered spark of shadowflame is not dropping from the Malicia’s Hoard, after attempting this for several weeks. The item is not hiding in my reagent bag / bank etc. Any recommendations? Kind of frustrating because I need the spark to get an embellishment.

Is it on a boosted character

I can’t even remember tbh. Maybe? Not sure but possibly. Does this affect it? I have the sparks/splinters on my main character, but can’t seem to get them to drop on this one.

I read other posts on social media about people having this issue and a few of them commented that it was on boosted characters… but recently boosted.

I see. I filed a ticket but they said to submit a bug report that you don’t hear back on. I figured I’d check the forums in case there is something I’m missing in terms of other quests needing to be completed etc… maybe it is the boost factor, you could be spot on there.
