I cant launch my ships!

[Will Badbreaker]

I had my ship get stuck when I ported and I fixed it. I was unable to repair it or use another ship when porting, so I went back to it, made sure it was not set to public, etc then asked anyone left on it to leave. (I don't know if that matters or not but I asked them to leave)
Then I switched to a quiet server and bingo my ship was released.
It is definitely a bug, I heard it can be caused by someone joining your ship just as you are porting. So a fix might be to make sure you uncheck the boxes for public at least when porting.
