When receiving a free zapper buff, there is no indication on the page or event/notification sidebar. Only when the buff expires, do you receive an event/notification.

The current work-around is to use the human zapper, then go right back to the human zapper page. When you click and have the free buff, you get another zap immediately. If you do not have the free buff, the page gives you a wait time.

Thank you.
