Missing I70 DoH Headpiece

Missing Item I70 crafter headpiece after previous patch, been redirected here multiple through in-game replies. Basically disappeared during patch and was not existing in bags or retainer after checking. All my crafter sets did still have them on as item to use.

To clarify this was not during the patch on 29.07 but on the previous one. I have been previously sending in-game support but have been redirected here.

I could redo it however, since I have already done this I'd rather have it fixed.
