Cannith Challenge items with the craftable property are no longer respecting Masterful Craftsmanship. For example, tier 3 Rock Boots at level 16, with Masterful, are minimum level 14 on Live, On Lamannia they are level 16. They retain the Masterful description in their list of properties.
I also tried reapplying Masterful at the crafting station but the Rock Boots remained minimum level 16.
Expected behavior is that Masterful lowers these items to 14 as they have always done on Live and as they were explained to function when Cannith Challenges were introduced.
Bug report also filed.
