no worries about the delay cryptic :) would rather have it done right than have it rushed which could cause you guys to miss something critical to the functionality of new content :D thanks for all of your hard work :)
the interface on the dread ring boon screen is glitched on some peoples screens. the boon grand master thayan technique may be located off screen above the main screen, try to drag the whole boon window down a bit and see if you can see the image of the grand master boon to collect your reward, hope this helps :)
