I just missed 14 rounds for Ragnarok. It started an hour early, again (so it started at 18:00) I was online at 18:00 because I knew it might start early. It's just that the Rag icon never appeared in my icon list, nor did the notification for the event appear.

Fact is there are two sections of icons in the upper screen, and you can switch between them by clicking the yellow arrow. If you're not in the right section, you don't see the icon.

That normally wouldn't be a problem, but because event times keep changing, I didn't think of looking into the other section.

EDIT: I knew it was ragnarok because someone achieved an 8 kill streak
