I also placed down a basic roboport setup with some rails and stations in a storage chest, to demonstrate the bug.

I then blueprinted the rails and station, ordering it to be built by construction robots next to the existing one.

I expected this to copy the name I gave to the station in the blueprint, "Station A", and so be a possible station to any routes that would pass by that station's name.
Instead it seems to simply forget the name of the station, and seems to happen every time.
I have also tried this in a normal game, where I first noticed the bug before reproducing it as above.
I have attached the log file for the session where I did this.
