Huge Blue Line Infront of Ray Mechanic When You Dash

[Cinder]

It only appears on the Rhoto-Whirl part of dashing, once you are moving around in the *dash* part of it, it disappears.

So i figured out what causes the huge line, I moved my costume pieces to a new character to level up faster and found the same effect was still appearing
The huge blue line is coming from when you have [Sweet Wave Sound Decal] It is not RM specific
