This happens every once in a while while I pk. As we all know, we can shoot arrows a lot faster. After I use Dark Pursuer, I press S and continue using Dark Pursuer. The arrow should follow the target. But the problem is that sometimes, the arrow does no damage at all and uses up my MP. I see the target, there are no rocks/trees or anything between us, and I am positive I am not lagging. This happens for like 10 seconds or so then it gets back to normal. I also tried letting the whole animation cast, by not pressing S, and it still does no damage.
Does this happen to anyone else too? Any solutions?
