[Gameplay] Galio Ultimate Bug fails to dash to target area

Basically what happens is, Galio targets an area with his ultimate but after he goes up into the air his wings don't glow but he still does the dash animation and then he just floats back to the ground. No other commands can be issued when galio ult's since he is locked out of flashing and doing other things I have no idea as to how this broke galio, I tried testing the wall and ulting over the wall however I had 0 issue with it, so perhaps it is champion specific with rengar.
