I was at the park yesterday, and yeah N:ST was closed all day. Air was off for a good couple of hours in the afternoon, got on it when it reopened and it broke again. Was stuck outside the station for a few minutes.
I was also at the front of the front-row queue for Rita when it broke too. They advised people not in the station to leave, but after 15-20 mins or so they shut the ride and gave out priority passes (never used it as no queues on anything but Air and Rita!) It remained closed for ages but looks like it reopened 30 mins before park close, which is awesome as they could have easily just not bothered for the short amount of time left
