My friend, unexperienced player, undocked ships that were in a factory and under construction.
He said there is message in production menu that the ship is missing.

My question is how to put these ships back to the factory?

We tried to use tractor beam of the factory, but it didn`t show any ships to use on. If it`s the right way to put them back: is it implemented?, bugged? or ships need to be assigned properly somehow?

Thank you for answers
