Overdraw bug fix when?
Disable the skill for now if you can't fix it right away. It's sort of alarming this isn't hot fixed yet. Having a unintended 1 shot in the game is pretty bad.
For anyone who's not in the know, If you use Overdraw and Quick shot at the same time, it will shoot 2 arrows simultaneously, while the final shot in the animation doesn't actually shoot an arrow. On longbow this is especially overpowered.
