According to various event timers this event has failed on Fort Aspenwood 36 times (http://guildwarstemple.com/dragontimer/events.php?serverKey=111&langKey=en) so I think it isn’t occurring anymore for some reason. The last time I ran it was 2 days ago so I’m guessing it failed sometime between then and now and just never proc’d again. Anwyay, I’ve been waiting for over 2 hours and nothing has happened which is why I suspect a bug.
