I purchased all the available Exobyte Origin gear and plans for the enhanced gear at the Anniversary vendor on my main toon, crafted the enhanced versions and equipped them. No feat. When I checked, I saw the head piece was missing somehow, but I also found it was no longer for sale at the vendor. Odd. I went to the vendor on a different toon, bought, crafted, and equipped the head piece on that toon and figured I’d finish it the next day. Today I bought the rest of the gear items (for the 2nd time) and then found that there was no record of the equipped Enhanced Exobyte Head piece, no record of the crafting plans, and no longer any head gear item in the Anniversary vendor. So I’ve spent a ton of marks and quarks for the antimatter motes (twice) and have no feat to show for it.
