[Gameplay] Turret/fountain range inaccuracies with Cho-Gath 6 stacks

On Summoner's Rift, as grows, so does the range indicator on each turret. However, When standing just inside the range of each turret or enemy fountain, they do not target me nor my allies even though it clearly shows them inside of it. This has been ongoing for as long as I can remember(Back in season 3 when I started), but has yet to be examined as far as I know.
