/tp_to and /change_sector cause me to be invisible to other players until I relog. I used this command once in a large ship, and a terrible bug happened where (after I had to relog) a chunk of my ship around the core was all i could see on my screen, seemingly in another "dimention" than the rest of my ship which became visible (minus the chunk I could see) to the other players close by. I was able to delete the section of my ship I could see, along with the core, as if the rest just wasn't there, while other players were able to attach build cubes to the other part of it (still invisible to me) and deconstruct it. After relogging again, there was a nav point for the ship in empty space, even though no parts, blocks, or core remained to represent it. /destory_entity had to be used to get rid of the ghost signature.
