[GAMEPLAY] Skills/Skillshots Not Going/Targeting where intended

Sorry, I can't provide a step by step, but I wanted to try something on the forums.

First of an explanation of my problem: I have been missing a large amount of skill shots from which I believe are reasons out of my hands, ie I'm garbo, bronze, etc. I managed to clip it happening once, but I may have another or two buried in a folder of games. The linked clip is live during a game, and I clipped it out, compressed it (sorry for quality), and uploaded it to youtube so we can start compiling evidence.

Secondly, I wanted there to be a place were all of us could drop in evidence of it happening in various games. I am positive it has not only happened on Howling Abyss, however, I have noticed it being more prominent there.

Lastly, the running theory as to why it is happening: we figured it may have something to do with unit collision. There have been semi-recent changes to how you collide with units on the map, and the influx of "I swear I'm not crazy, that went nowhere near my mouse" moments seems to be directly related to those changes. In the clip, you can see me (Fiora) colliding between the Nautilus and the turret, and in that time, my snowball flies wide from its intended target. I clicked on Nidalee, with visual confirmation on screen, yet it flies towards Malzahar, which is vaguely in the direction of the collision.

Good luck on the rest, and hopefully we can see some more responses to gather more on what might actually be causing it.
