New validation error, clawhand shield

[Hykim]

Clawhand Shield is failing validation with the error, "Mithral: Requires a Metal item." There is no way to change the materials of the shield if I View/Edit the item. Selling and repurchasing the item does not help.

I'm not sure if before this patch I had modified the material to be Mithral and that is causing the issue. The fact that it is happening on other characters if I buy a Clawhand Shield makes me think it is not due to that though.

Reporting as a bug.
