The final price of the GreatSword is much lower than the price to create it, all GreatSwords that I selled cost only $7 to $13, but to make one I need to use more than $33 (all other weapons look ok)
edit: one hand sword sometimes have this problem too(not always, when it happens it apears as One hand sword instead of Bronze One hand sword)
