Attack on Move bug

N/A Screenshots or videos Need to get other's to test

What's happening for me it seems is that when you're trying to use Attack on Move for let's say a champion that can be dependent on the mechanic (e.g Kalista) the targeting won't go for champions, scuttle or will prioritize further enemy's then closer to the move icon at seemingly random.

I'll try and get some videos in an update but I have no screen capture service
