Was turning in the quest for this item https://www.wowhead.com/quest=53171/battered-twilight-scale
I had a few of these in my bag lined up but the quest turn in seems to have consumed them all and I only saw UI feedback for single reward (gold + 700 Azerite power).
Not concerned about the loss to be honest, just wanted to flag potential bug (tried in game but everything redirected to external forums).
This was handed in on posting character.
