Seen others hit by this. Sadly with me it was Quartermaster Hargrove (story mode token vendor) and so far I haven’t seen anyone get an item swap/refund. As far as I know you only get one of these tokens per char. I have sent a ticket- wish me luck or my ele will be stuck with an unusable harpoon gun (lol).
Basically I clicked preview, but it spent the token instead. It seems with most people this happens with the race armour.
