The latest patch changed Boneclub stats but failed to update Bone Cudgels as well. The same thing happened with Maces getting changed while Sun's Grace and Flail didn't. (This is not unlike a past bug where the Pickaxe got its combo changed to 1 while Diamond Pickaxes still had a combo of 2). I am unaware if any other weapons that got stat changes in the latest release failed to update their uniques, needs investigation.
