I hope this is the right thread.
I love to build lots of station and docked them to mega complex. The problem, some freighter A.I can´t docked on this station and get in parking line.
i learned that the docking port for each station must be outside of the orange docking box ( the box that can be see in the build mode)
I got some picture.
That is not a real game breaker or game problem. I think the easiest way is, that ship got a counter that the jump away (despawn) after 10 20 minutes.
