Ah sorry, so this isn't very obvious. If you define an animation set that means you have individual animations for every direction, so the way you have defined it the game will look for "channeling-west", "channeling-north", and so on. What you want to do is change the <string name="chnl-anim-set">channeling</string> to <string name="chnl-anim">channeling</string>, which means you only have a single animation no matter the direction.
