I have a problem with the amount of Spark of Ingenuity. On the main character (Aerethe - Silvermoon) I made an achievement - In Tyr’s Footsteps (25.1.23) . Until now, I wasn’t interested in how many Sparks I should have until I leveled up my alts, which currently have 5 Sparks each. I counted on the main character and it turned out that I only had 3 Sparks so far, 2 of which I used in The Artizan’s Market. I made an order for the neck and ring. Now I only have 1 Spark in the Bank. What have I done wrong? Why do I now have 1 Spark and not 3 Sparks. Can You help me? My main character who has a problem with the amount of Sparks is Aerethe on the Silvermoon server. All my alts have 5 Sparks.
i have similar problem, 1 of my alt char has 5 Spark of Ingenuity, the other 1 has none, they just did not apprered in bags, and main char has only 2, but i used 2 of them for crafting. my main char also missing 1 Spark of Ingenuity.
Got one from Bisquis, the Tuskarr cooking event.

You are welcome. 
And, thanks, Blizzard, finally I have a chance to slowly max out my blacksmithing.
