Thanks for the feedback… When you jump from place to place you might get some issues - I do a lot of jumping for testing purposes and occasionally I also see eg that no ships load at all. Of course neither the sim nor this addon is optimized for jumping around loading the whole world, but if it happens, then the cure is as you did. Restart. Anyway I recommend just using the regions relevant for the flight to keep stress on the computer as low as possible. The spinning issue will be resolved with the real time version, where we will however introduce other small visual annoyances 
but also some great sights… here testing in New York Real Time yesterday…
