Hi There, I upgraded to Mountain Lion a week ago and I moved all my calendars onto iCloud. All was going great until today I received my first event invitation (.ics) from Google Calendar. The problem is when I click the invite.ics file it pops up in iCal with an event from way back in 2011. An event someone else invite me to (also through Google Calendar). I have opened the .ics file in Textmate and the date stamp is correct, it just seems that iCal is linking through to a phantom event in the past for some or other reason. I have attached 3 screengrabs. One of the email in Apple Mail 6.0, the other is the screengrab of the event in iCal 6.0, and the other is the screengrab of the invite.ics attachment. I have checked my Apple account and I only have 1 email address associated with iCloud. Your help would be appreciated.
