Gangplank - CS Bug

While playing gangplank, I've noticed that my CS score will suddenly drop from say 400 to 325 or something, at random. I know that I'm not the only one to come across this bug because I've seen some other posts about it. Although it's not game breaking, I find it to be very annoying and deceptive. I can't really tell how well I've farmed if my CS score is always dropping. I hope we can bring some attention to this. ^_^
