On the Keys of Loyalty quest, farmed the prerequisite frames and fragments, combined it, got a text message in chat saying I got it just like how you’d normally see a looted item appear in the text chat, but nope, nothing. The materieals I painfully farmed for were simply deleted and no quest item given. Strangely, my “Combine looted fragments to create a key” step is at 1/1, but no key ever appeared in my inventory.
As an FYI, if I try to use the link in the “How to report a bug” or whatever it was called, that takes me to the US bug report forums. Where I cxan’t submit anything as I don’t have a level 10+ character on NA. And yes, that’s where I’m taken from the EU battle.net site. This should probably be fixed as well.
