This is the third time I've seen it happen now. I tell the CV to build the station. The Captain flies the CV to the deploy spot and then stops. Nothing else happens forever. I let the ship sit there for almost 3 hours and it did nothing, despite the Architect having the build plan up for the station.
I tried unsquading, resquading, telling the captain to stop, continue and do the macarena. Even talking to the Architect directly and telling them to cancel construction didn't work. The ONLY thing that would work to get it moving again is if I clicked on the build icon itself in space, selected Build and then told the Architect to cancel construction. At that point I got the normal station build options again and could tell the Architect to build again. At that point the CV moves a half inch then started building the station.
It seems like every single thing I tell a ship to do needs constant babysitting and kickstarting through random and unknown ways that differ for each task and station.
