The Hidden Forest

I have been in shadowhaven for awhile trying to get all the parts for my automation bot and have racked up quite afew radiant crystals. At first I thought they were different than the currency, yet when I accidentally clicked on the 15 I got as a quest reward they turned into the same unusable item I was picking up. I put them on my pointer and pressed the reclaim button, nothing. In or out of bag, nothing. What or how do I use these?

- Thankyou

Head over to The Hidden Vale. Merchants there use crystals as currency.

Just tested with UF client. Was able to reclaim them without them selected and with them on cursor by hitting reclaim button on main inventory tab
