Second Spark of Fortunes available through bug?

Somebody in trade chat asked for a recraft on their staff. Without thinking about it, I told them I could do it and recrafted their staff to 658. Then a few minutes later, i realized they shouldn’t have been able to have 2 sparks yet, so I asked them how they were able to get a second spark when there should only be 1.5 sparks available this week.

They said they weren’t entirely sure, but that they had 2 splintered sparks in their bag, they combined them to create a spark, and then they were able to turn in the quest near the catalyst to get 2 more.

Since i didn’t realize it was odd until after I had completed the craft, I unfortunately do not have screenshots to prove it
