Known Issues
Some items have border issues:
 * Winter's Wrath (upgraded and epic): Has a silver border. Lacks a gold-border. Gold Border usually denote unique items, which it is.
 * Midnight Greeting (upgraded and epic): Has a platinum border. Platinum borders usually denote a raid-quality item. This item is no where near raid-quality. Should be gold.
