[GAMEPLAY] Nidalee spears not connecting- ARAM only?

So I was playing a game of ARAM, and I was Anivia (blackfrost skin if it's important). The Nidalee on the enemy team (default skin) was throwing the occasional spear, and every now and then spears that should've surely hit me didn't register as hits. I didn't take damage, wasn't marked, and no hit sounds came.

The few things I noted:

• It seemed to only work when I was moving in a direction perpendicular (or at least near perpendicular) to the spear. Moving in a diagonal roughly 45 degrees to the spear direction or moving in the same direction as the spear would always hit.

-It only seemed to happen when I was "stutter stepping" for lack of a better word. When I was moving back and forth (perpendicular to the direction) rather than just moving unidirectionally, I wouldn't get hit.

-It was hard to tell if the spear would still exist if it went through me. All of the instances where it didn't register were near the end of the spears' travel distance, though it was still pretty evident I should've taken damage. Nobody was close enough to me when this bug occurred to know if they would've taken damage. This means I don't know if the spear was going through me, or if I was making the spear disappear.

-It didn't happen in every instance, provided that my understanding of the bug is correct. It was roughly 50% of the time though.

-If you applied cardinal directions to your monitor (so moving north would go off the map, I believe you go east+slight north/west+slight south to stay on the howling abyss lane), I believe this bug only happened when I ended up facing the southeast direction. I didn't remember any instance of me encountering the bug when I ended up facing the northwest direction. This I'm not positive of though. When I tried to recreate this in game (stutter steps, perpendicular travel, end up facing southeast) I did keep taking damage.

Maybe it's just a hitbox thing, but it feels wrong. Unfortunately I don't have any capture/video of this :\ I'm a little pressed for time now but I might try to recreate this in a custom in the next couple of days.

Thanks!
