Divine Ire bug makes it near un-useable

When releasing the divine ire beam and rapidly re-casting the spell to begin channeling again the character gets stuck in a state where it stutters and visually seems to be rapidly cast the spell and firing beams out but no damage is being dealt and the character will not properly cast divine ire again until moved. Yet the the mana for the skill is still being spent when in the ''bugged'' state.

Very easy to replicate it happens to me accidentaly several times per map if i'm not careful. The bug severaly affects every moment of gameplay
