There is a bug where you do not gain gold killing other champions. Just launch the practice tool and kill another champion and you will see that you do not get any gold for killing. Also the bounty system is broken in the practice tool only
External link →Hello! We have a fix slated in 15.2 for this. Thank you for letting us know. :)
This issue is still happening on live client.
Yea, unfortunately the fix was overwritten. :( We are trying to find a longer term solution to avoid it reverting in the future along with updating the next patch with the previous fix
