Usually, here's what happens. There's on average about four people attacking rowdy at the same time. So when he's just coming out of the hospital:
The attack button is clicked Then, several attempts are made to initiate the fight The weapon is pressed multiple times, followed by a prolonged delay (lag) of approximately 5-6 seconds Finally, the screen is progressed, to the "ajax" error page 25 Energy is still lost, with no compensation
I just checked your attack page load times (server only), it's all between 0.2-0.4 seconds, this looks not like a lag issue. Can you please tell, if this happens on a single server every time or on different ones? Perhaps in some specific time?
And what you actually mean on "several attempts are made to initiate the fight" - start fight button is not working when you press it?
Accroding energy spent - if attack is still you active you can just refresh the page, such error will not cause it to end?
The fact that load time was fine in all your attacks during last 3 days can tell that this is a client-side problem. Will be good, if you will continue to report, if such things will happen again (you can mail me directly with all required info).
