The Weatherstock prizes for bands have been sent out via in-game mail on Landroval. Please stop by and pick up your Turbine Point code.
If you don't have a mail message, check to see if it has been sent to one of your alts. (I used the names found on the Weatherstock planning document.) If you have a problem with your code, please let me know which code you tried to use, so that I can check it for you. Thanks!
