After finishing this feat, I expected to see a similar feat with an upgraded number of objectives and a slightly different name. However, the next feat has the exact same name. It does increase the count from 33 to 66 though. I have a feeling that these are supposed to be two different names, like Myth Hunter Rookie, Myth Hunter Expert, and Myth Hunter Master in Amazon Fury Part 1.
I imagine the feat names were supposed to be 'Sneaky Spray Apprentice' , Sneaky Spray Journeyman, and Sneaky Spray Master.
Added to the bug tracking site with the suggested names for the different feat levels. https://dgcissuetracker.com/browse/DC-2738
