I've noticed that when a notification appears in light green at the top of any story war page you happen to be on, it only stays on for a 'short period of time'. By the time I go to click on it, it's gone in a FLASH. So then I go to my notification section under my profile, and more times than not, the notification is not listed.
Could the notification appear longer than before, and maybe in a different color, to better attract attention. Unless one is actually looking at their computer screen, they'll miss the notification.
