When the interface for the Atelier was updated to use sliders to indicate how many you want to purchase (up to 99) rather than having to make repeated single purchases, the interface was not updated for purchasing Carved Ebony Wood. It will uses the old way of choosing to purchase, then you get the confirmation that you want to purchase it, then click OK, then click "Buy" and repeat. I'm not sure if this is true for the other carved woods or not because I have not tried to purchase them. I have been purchasing some Carved Ebony Wood from the Atelier as I have time to sit there and click "Buy" and then click "OK" thousands of times across mine and my wife's characters.
Most of our characters are L25 Artificing and Carved Ebony Wood is one of two components required to make crates to donate to the guild for surplus equipment. I'd like at least 5k on each character, but with 13 characters between us, that is a serious time investment and one that is seriously hard on the hands and wrists. Please fix this!
