Runaan's Hurricane bug

Runaan's hurricane is supposed to hit targets near your initial target with the additional bolts in a range that extends from your target.

Since the preseason however, the bolts only hit targets that are within your attack range.

For example, lets say I'm Ashe and I have 600 range. I hit minion A 600 units away. Minions B and C are 100 units behind minion A. Before the preason, both minions B and C would be hit. Now they are not, they are only hit if they are within 600 range of you just like your target.

Additionally, Runaan's hurricane seems to not be interacting with on hit effects correctly. Notably, Ashe's Q passive does not generate stacks from the runaan's bolts, and I've heard but not tested that Caitlyn's Headshot passive is not gaining additional stacks like it used to either.

The video I provided shows how Runaan's hurricane functions at various ranges. The key point is that at maximum range (0 - 1 seconds in the video for example) no minions except my target was hit.
