Spark not working properly

In normal circumstances when I cast spark the projectiles fill the room very quickly, allowing me to kill mobs effectively.

While holing down the mouse button to cast spark continuously, the projectiles start disappearing and not killing mobs, as there are not enough of them, this is becoming very difficult to kill higher tier mobs, because as the projectiles are not casting a at a consistent rate, I end up being killed.

As this is erratic and it is on and off I cant say why its doing it, I did see a video of the same issue I am having, posted posed on reddit, see below

Please fix as this is becoming unplayable for me, as I need to progress.

Same issue happening here. Have you found a solution yet? I'm at the point of making an entirely new build.

I have tried different maps and environments, nothing seems to work, I hope this is fixed, as a spark build depends on the number of sparks as a whole and any thing that diminishes this, will cause the build to be weaker than it is.

I am struggling when the sparks don't shoot out in manner there supposed to, a lot of occasions I have been killed, due to a lack of sparks, I will have to share my own videos showing it.
