Gameplay - Shyvana Bot Walking Through Wall

Not exactly a major bug, but I was playing a bot match yesterday, and on multiple occasions Shyvana Bot walked through the terrain at the right of the map, near purple sides outer turret, just below the tri-brush. I've seen things like this happen a few times over the years, but they were generally lag related and just visual, or have literally only happened once in the over 5 years I've played league. But this happened to Shyvana Bot 4 times in a single match, all at the same spot.

Some other information each time it happened: -She was in Dragon form. -One of my allies was in the tri-brush/the general area of the brush, and she started on the side near the turret.

I circled the wall i am referring to. http://postimg.org/image/4lbtwu1oj/
