EncArrow4DwarvenFireDamageLight, Arrow4Dwarven, EncArrow4DwarvenSilence, EncArrow4DwarvenFireDamage, EncArrow4DwarvenFrostDamage, EncArrow4DwarvenShockDamage, and EncArrow4DwarvenFrostArea are all incorrectly pointing to the menu icon for iron arrows which Bethesda included but apparently never uses.
Love this change that makes the enchanted arrows use the correct Dwarven icon. It also mentions an icon for iron arrows. It should probably be assigned to iron arrows. I think iron and steel arrows usually have the same menu icon, so if the unused menu icon for the iron arrows is not broken, it could be assigned to them.
