First thing, what is the error message (if there is one) when you try to move? Or are you saying that there is no option to move? As for the ship, are you sure its moved? If you have been hopping between buildings, then its possible that the building you are in is no longer near where your ship was and so you cannot enter it from there.
AH. Well if anything has an error message like that its best to head straight to the bug base as there is nothing we can do to help - you'll need admin assistance to fic your issue. Usually those errors say to go to the bug base anyway.
