Master Yi ult doesn't play the sound effects

Hiya Riot,

I've been aware of this bug for some time now and thought I'd give you guys a heads up:

When Yi uses Highlander and the duration of it is extended through killing an enemy champion (Quite often multiple times); sometimes the sound effects of the ult will stop playing after the ult's original duration or a few seconds before it should.

I'd like to give you better details, but my limited knowledge about coding won't let me test any further. Therefore, I'm sorry to say the bug does seem to happen without consistency that is noticeable on my part.

Not a big issue, but seems to have been around a long time. Thanks!
