Yes, I reported this to the SCISS people via Sara back in June after they fixed the bug in v 1.6 that prevented me from going to a "BCE" year. It appears that the star catalog is precessed correctly, but the grids are not precessed. For example, when I go to 2800 BCE, the night sky does indeed rotate around Thuban in Draco and not Polaris. However, when I bring up the celestial coordinates grid, the N.C.P. is still marked at Polaris. (So I keep the grids off.)
I have been hopping around to different locations on Earth in "Sky" mode many times the past two weeks for our intro Astronomy classes. What I have done is create user Surface Locations for the North Pole, Tucson, Equator (Quito), and Santiago de Chile and define the azimuth angle the same for all locations so that the cardinal points stay at the same location in our theater. One can right-click on the Surface Location and select "jump to" within Sky mode and you go right to that location without ever leaving the ground. (However, I tend to select "fly to" since I believe leaving the ground and flying to various locations on the Earth's surface give the audience a better sense of where they are going.)
