There is still a bug to complete the last part of Enforcing Fate. 0/1 Potion Swapped It doesn’t matter how many times I do it, it won’t give me credit. I did a Google search and seems it has been a bug for a long time. Blizzard recommended abandoning the quest, making sure there is room in bags and doing it again which I did and still no luck.
I abandoned the quest and opened up 5 extra backpack spots after re-accepting the quest and it fixed the bug!!!
