Issue: Aiming circle to throw demonic bombs to destroy the duerger shrines is not visible in play mode, and therefore cannot be executed. Compounding the issue is that if you alt the screen, or open inventory/character/etc, it becomes visible in the dimmed background. Also compounding the issue is that other players are observed to have no issue with this quest.
Attempted: Have dropped and requested quest several times. Have also logged off and exited game several times. These have not resolved the issure.
