It appears as though the url alias system didn't catch here, I'm not sure why it didn't. Since you've had 15 events named "Angels Guild Meeting" this new one should have been given an alias of angels-guild-meeting-16 but instead it was simply angels-guild-meeting event which was the alias to the first meeting so named. To get around this for the time being until I can look it try to title events with something unique, like Angels Guild Meeting Feb 27, 2015 or whatever.
Can you remove the present event on the Calendar please? I'll do a do over. thanks.
