Merged report from @33Cav contains more information:
#1
Using the /load command will result in a C aligned spawned station, even if the saved station was not C aligned so that works.
However, using the "spawn station block" button and buying one for 1 million credits will result in a 90 degree rotated station block relative to the C alignment.
The spawned station block will be aligned towards vector (-1, 0 ,0)
The C alignment is aimed towards (0,0,1)
#2
no way to align a station in a different way when spawning it in from a bp.
