even now I still produce unmovable cores. But only on the server. In a local game there s no problem

Thank you, but now there is (still) a problem: if I dock a entity to another one and move this one with rails around, I cant undock it again, after another reloud the entity is there, where I picked it up. I am building a device to lift containers out of ships and store them in my station. I have the full range of motion:left right forward, backward up and down. And if I want to undock a container from the moving part to store it somewhere, it gets stuck. It doesn´t react to any pressed keys. thats the most important issue in this bug

But is there a way to undock the entity from the rail? You just showed me the way I can undock someting from the station and catch it back, I want the docked entity undocks itself from the rail somehow.

And the station. just push the button

thats the logstarmade.0.log thing

and while playing with it my game crashes quite often. And I keep producing zero-poiner-exeption-Failures. can somebody thech me about them?

1. No. Its completly frozen and can´t move at all, even with a pilot controlling it. or even deleting everything exept the core, its still not possible to move it.
