I can’t seem to find a bug about this but since the last patch Argos the notification timer has been out by 1 hour. I have seen quite a few people having the same issue all grouped up at a spot and nothing happens come back an hour later and its there when it still has an hour to go.
I think it is from when your own timezone is in daylight savings the game is incorrectly applying that to the server time or not taking daylight savings into account when calculating from your local time etc…
