Base armor class crafting bug

[Jofuss]

Similar to the bug previously reported and addressed based on item durability being carried on from base item to crafted item, the base AC seems to also be carried along as well.

Example:

I take a Royal Circlet crown with a base AC of 40 and craft a new crown from it. It recieves +100 percent defense and now has 80.

While this may be intended, it could easily be abused using such an item to create a much stronger item using specific base unique items.

It would seem to me that the base AC should be "rerolled" as well during crafting.
