In released version, WD failures say something like "Your target did not need saving" (going off memory). In the Test version, it says "You failed to convert your target" meaning WD now receives the same failure msg as a Cultist. Not sure if that was intended or not.

I don't recall, what is the released version's handling of the case in which WD heals a role that is not convertible to Cult (say, a mason)?
