There are two known glitches. First of all there's a glitch in the beginning part near 5000 BCE when the Phi goes down and second of all there's a glitch in 9000 AD when the Phi moves up too rapidly. The sun goes in the wrong direction in the sky both times, either moves forward too far or backward when these glitches happen.
Also the planets all have their skys gliched up every time the calendar on Starry Night returns to January 1, not necessarily January 1, but January 1.
