I was organizing an Event two weeks ago, with a few friends of mine. There were 188 trackable items... and that GC. When I saw that the owner does not want it to be part of Events, I had to refuse it 🙂. The guy who brought it in was a little surprise, but you are the owner and you do what you like 😉 Thus I retrieved it from the official list of trackables for the Event.
Kind regards from France,
