Short version: after activating Camouflaged Hunter and killing Daedra (to ended the duration) with a bow to extend its duration, the Camouflaged Hunter animation will play again repeatedly in random intervals (seemingly between 5 and 80 seconds). If the animation plays the current attack (heavy or bow skill) is interrupted and now played. Please fix!
Longer version: I have discovered that I love using Camouflaged Hunter to wipe Daedra off the face of Tamriel. However, use of this skill has a rather irritating (bugged) side-effect: the animation will play randomly (interval seems to be between 5 and 80 seconds). While spontaneous dance-looking grooves aren't necessarily a bad thing, if the random Camouflaged Hunter animation plays while I'm holding a heavy attack with my Bow, or in the middle of a Snipe animation, my action gets interrupted/canceled. This is a bummer and kills the flow.
