The issue is that it’s impossible to add an embellishment to a crafting order.
The embellishment slot in a crafting order, when I mouse over one, says: “This optional reagent slot can only be provided by the customer.”
Is it possible that you provided one either automatically due to an addon or by accident?
When I went to check that, I found the behavior fairly inconsistent. There were periods where I couldn’t fill an embellishment slot (much to my chagrin as I had to cancel and re-submit the work order to my crafting character), you are currently able to provide one through public orders (I placed an energy redirection beacon onto a cloak I posted in a public order). It could be a bug that I was unable to place it before, or it could be bugged now, or it could be neither.
While I can understand the frustration, there isn’t a way to refund a work order. If you think there is a bug, you can file a bug report, but it is unlikely that will result in a change to your personal item.
In the future, if you wish to ensure that no embellishment is placed onto a piece, you will want to provide an embellishment remover, Griftah’s Heavy-Duty Embellishing Powder for this expansion, which will fill that slot instead of leaving it open to the crafter. You can find that at Griftah, between the Forgegrounds and the Weaver’s Lair tunnel in Dornogal. Unlike other items in the slot, it won’t affect quality and won’t make the item unique equipped, so you can ensure that nothing gets placed in that slot you do not wish to be.
Well that’s just frustrating. I made sure to check it prior to posting and the public order wouldn’t allow me.
Maybe just maybe if you do not pick a embellishment it will add a random one and then you can end up with something you really do not want.
Hey, Im on Moonguard. I can take it off for you. You need to provide the acuity tho for recraft or i can use mine for 5k if that’s worth it to you? If you send me an order lemme know here. Shoot it on over to Gothitrix on ally. I gotchu 
No I didnt add it. Id never choose the grenade embellishment anyway.
It’s cheaper to get new mats and send for another order.
Then Blizzard would be the one griefing.
Is this actually what can happen?
no lol but based on my experience, you are able to add embellishments as the crafter
i tested it on my own alts, sent an item to be crafted and my crafter alt added the embellishment
thanks for confirming, appreciate it
from now on I’ll add that Griftah’s Heavy Duty Embellishing Powder to prevent it from happening again
No that’s not how it works.
