I am missing one Splintered Spark of Shadowflame. I believe I missed the reputation quest week 1, which is my fault. However, I have fully cleared every difficulty of raid but mythic every week, done 50+ keys, and all world bosses and have yet to receive my catch-up spark piece. I have had multiple people check my account with me to make sure its not missing, and would like to craft an item next week for our Mythic Progression.
