I'm encountering a bug where upon enchanting Saint's War Armor with Fine (+2 damage reduction) it no longer seems to apply damage reduction for piercing. The stats of the armor show the +2 DR being applied to overall DR, slash, pierce, and freeze, but under character stats the pierce damage reduction completely disappears.
Images of armor and player stats before and after Fine enchantment:
If I'm misunderstanding something with the game mechanics here please let me know. Otherwise, I guess I'll have to hold off on the enchantment.
