Druid level 46 damage add spell, Hooks of the Wild is not refreshing upon cast. For example; if the current buff has 2:00 left on it, casting the buff again does not refresh duration. You have to remove the buff and cast again. I don't think this was a problem with the lower level spells.
same issue with the level 27 damage add spell, Pincers of the Wild
