Not sure I understand. "seems" "kind of"? Are you able to move things from one space center to another if you order your shuttles to do so or not?
I know that I have not experienced problems moving things, if I so order it. I just need to understand what your expectation is, and what is not happening. It is not clear to me why there would be any question of it not working if your transportation orders just sat there for an extended period.
