[GAMEPLAY] Thresh and Kalista's W Passive

There seems to be a bug with thresh and kalista's w passive where she marks a target then where then the support autos the creep. When thresh does it, most the time the gold goes to Kalista but every now and then (I would like to say 3/10 times) thresh gets the gold. I believe this has something to do with Thresh's E passive. I will work on getting a video of the bug in a second.
