It's very unfair when Stark Assignments aren't displayed. [Not A Bug]
Sometimes the game doesn't display changes. With new events, this isn't a problem. When the new monthly event comes out, I restart the game after the old one runs out, and there the new one is. With 7 hour events, it's slightly more annoying, but I know there's supposed to be one, so I can restart my game if it's been a couple hours without one.
With the Stark Assignments, it's a big problem. They're random, so if I don't see them, I have no reason to think they're happening.
I just checked for one at 7:15. There was nothing. I even went to the home screen and went back, just to be sure. So I did other stuff for awhile. When I checked my phone at 8:45, there were only 15 minutes left. I had not gotten a push notification. So the new missions started without displaying and without sending a push notification.
I played as quickly as I could, 100% explored heroic, completed master once, then got kicked out of master with 3 more enemies to defeat. Since 100% exploration is what gives most of the rewards, this was pretty disappointing.
This is bad. If you're going to make the missions start at random times, they *have* to show up when they start. At the very least, put up a "Coming Soon" a half an hour before so we have more of a chance of having it show up in time.
