When Umberdroth hide appears as a crafting item, the hotscreen that appears when you hover over the item to reveal its modification effect reads "UnlockCombatAbility" rather than showing the actual impact (e.g. Attack +1, or whatever it is supposed to do.
In the crafting recipes screen, when the Legendary Amulet artwork is the same as for the Legendary Ring (i.e. a ring rather than amulet image).
Just wanted to report that when casting Vorpal Longbow as a Tinkerer (any size map/number of opponents), the Longbow appears but is labeled as "Vorpal Blade" in the unit box when it comes time for its action. Really enjoying the game and each update! EDIT -- Should have added updated to Beta 5.4 -- sorry!
