When trying to complete the quest “Fel Tanning” in Suramar for recipes that get Legion leather working to 100, I ran into a UI issue that didn’t allow me to complete the quest do to a UI issue which didn’t display the training option under Legion leather working when I picked up the quest.
SOLUTION:
I found these 3 macros that allowed me to craft the items without using the profession window
Fel Leather Strap Macro: /run PickupSpell(196395)
Fel Leather Cuff Macro: /run PickupSpell(196457)
Felhide Bracers Macro: /run PickupSpell(196456)
Make sure you create 3 separate macros (just replacing the number wont work)
