Not sure if this belongs to TR_Mainland or TR_Preview - it's a dialog with Hamal in Old Ebonheart, Hamal's Redguard Goods.
His every greeting is asking if the player's "come to see the fabled Shield of Mad-Hoosa's Gaze", even after having sold it to the player. I think it should be checked if the player has it, and give a different greeting then.
