tl;dr there is a bug and this is the first time i got an answer that it was infact a bug. this was after 6 or so responses from ai telling me to go to wowhead to make sure ive completed steps/etc, and to submit a bug report (i dont work for blizzard im not a game tester).
i cant post a screenshot, so heres the plaintext copy and pasted.
i’ll post a screen shot in a reply, gotta find an image site to host it so i can link it. i don’t post here often enough to know what the MO is. anyways:
Your ticket has received the following response:
Greetings Cadvr!
First and foremost, and as a player myself, I can fully understand how you are feeling right now since you are in posession of a Excessively Bejeweled Curio but can’t make any sort of exchange with Kari Bridgeblaster.
Now, I was doing a deep dive in your logs, and I was able to find out that there was a recent Bug which allowed Excessively Bejeweled Curios to drop from the Liberation of Undermine on “Storymode” difficulty, which was not intended. This Curio should only drop from Chrome King Gallywix on either Normal, Heroic or Mythic difficulties and only the ones dropped on the aforementioned difficulites can be exchanged with Kari Bridgeblaster.
With this in mind, and I understand how tough reading this must be, since this drop wasn’t intended, the Excessively Bejeweld Curio that you have in your posession is, in fact, not usable at all and, as such, you can safely delete it.
Once again, I understand how you are feeling, but I would like to encourage such a dedicated player like yourself to do your best and try and obtain the Curio though the appopriate difficulties. I’m sure that you’ll be able to do so in no time!
