If it turns out that after patch installation there is still no dmg increase in Expert and Master Spear I guess I will have to live with it...or I should say play with it... .

I will get Expert dagger then for my Archer and she will double wield - dagger and spear.

Or maybe there is a way of fixing that bug with the editor...? Does anybody know if it is possible? How do I go about it?

Or maybe I should forget about it ang for the dagger/spear and forgot about this stupid bug?
