NAM updates slow, "about data" contradictory

[stevecrye]

For several days I've noticed that moving the time slider in the Android app will not change the wind or other parameters displayed, only when NAM is selected. The "about these data" for NAM shows contradictory information, such as last updated one day ago, next update now, but it lists the next update expected for a time more than 6 hours in the past.
Also, the NAM forecast displayed by Windy differs from what I see in XCkies using NAM.
Also, normally NAM can look ahead more than two days, but right now it cant see more than about 30 hours from now.
