In order for constellation lines/figures/labels/boundaries to appear while in sky mode, each of the following need to be checked "on" in the layer manager:
"3D Universe"
"2D Sky"
"Show Solar System"
This is strange but needs fixing because there are times when you want to view Sky mode with constellations but no planets / sun.
*don't ask how long it took to unravel this as the reason that my tour was broken
