Forzathon Live Disappears

Twice tonight I have seen the Forzathon Live on the map and started to head there, and have arrived a couple minutes before the hour, but the location on the map had disappeared and never came back. The second time there were other players on the map at the same location, so I am guessing they were there for the same reason. I don’t see how it could be my settings either. Also neither time did I get a notification five minutes before.
