Hey guys -
I've looked into this one a bit, and it seems to be an issue exclusive to local matches. (Therefore, you would never see this happen in an actual game). Jungle practice is a useful tool, but it doesn't create a net instance on our server. Therefore, it doesn't 100% replicate a regular game environment. For most abilities, this is just fine. But some abilities rely on server response to function 100%, and in this case, you're running into one of those.
You CAN use jungle practice in a net instance, and that simply requires pulling a friend into jungle practice with you by partying up. And if you do so with Kali, you'll see that you'll consistently hit the triple hit at close range.
