My last post for bug report was close saying that it was fixed but i am afraid it is not. I might not have explained myself properly so i have made a short video for it. here is the link
Below is text from my last post:
In all the professions like tailoring, leatherworking, alchemy and jewelcrafting etc there is a daily cooldown on creating some specific items like Magnificent Hide. There are two spells that should share cooldown for its creation, Magnificence of Leather and Magnificence of Scales. They do share cooldown, but if you relog your character, the cooldown is gone.
