Ever since upgrading to Mountain Lion (10.8.2), I'm having an issue with my Calendar. It seems like all of the new meeting invites I receive are incorrectly associating with old meetings (2009 and 2010) on my calendar. I'll receive an invite for a new meeting. I'll click on the attached .ics file, which will take me to an existing meeting from several years ago instead of creating a new meeting on my calendar.
Is anyone else having this problem? More importantly, does anyone know how to fix this?
