Skins Missing
That screenshot isn’t very helpful in proving your case. We cannot see any stats on it. Take another one with you mousing over your equipment. That way the stats can back up your claim.
Thanks Zeivu, updated with stats however I’m not sure how that would help as prior to the April patch using a transmutation stone I transmutated a different stats over the one which the Fervid Censer has (I just kept the skin).
Short answer: you screwed yourself.
Long answer: You didn’t start with a Fervid Censer. You started with a Rabid Spineguard. You then transmuted it twice. Items that have been transmuted will only unlock the base skin (rabid spineguard, which doesn’t have one) and the last transmuted skin (your quaggan backpack). Fervid Censer is lost forever.
Assuming the devs haven’t gotten back to you about this, you can risk that they will grant you your fervid censer (they seem to be pretty forgiving, and you evidently have proof), or you can go farm some tokens and buy one while it is still available.
