What happened is that your ship was left in empty space, before the admins placed a system there. When the system was placed, your ship was essentially thrown into stationary hyperspace, a magical layer beneath the system. You need a support ticket so the admins can reset the position of the ship so it reverts to normal space.
its an unfortunate side effect of how the admins add new systems, yes. They make the system in another area of space (the admin sector at one point) and then c/p it into the new location essentially. Its the new system data that erases the previous empty space data.
