.ics files will not create new events

UID are (supposed to be) UNIQUE ID's. There is no other safe method for identifying one event from another.

For a test I downloaded the ICS files of their four currently published events and sent them to my never-used gmail account. I selected to add them to Google Agenda. Guess what, only one appeared. When I click on the others in the mail attachments they all go to this one.

So the problem lies in the way Rensselaer County Regional Chamber of Commerce create their event invitations, not in the way Apple or Google handles their malformed files. Tell that to the source of the files.

I opened all four ics files in BBEdit (TextEdit would do too), added -1, -2, -3 and -4 to their respective UID's and then Calendar correctly created four distinct events.
