PROJECT: Ekko Q disappears at max range

Don't have a video and enemies /remake'd before I could grab a screen, but PROJECT: Ekko's Q disappears while it's at max range. I don't have the skin so I can't test it myself, but against an enemy it happened. It almost seems as though the file for his Q projectile is missing, since you can see the path as it travels, then nothing, then the path as it travels back.

I've already had the client check the files, and it didn't find any differences.

How to recreate: Play a game against PROJECT: Ekko. (He did have the PROJECT loading screen border, if that matters at all [I don't imagine it would.]) Go into lane and have him toss out a Q.

I will try and grab a screen if it happens again.
