Hello.
The shipyard S/M Paranid and Argon do not build the ships (and they are full of materials)
The strangest thing is that the shipyards seem to be "being built" when all the modules are built and finished (the Xenon attacked those areas and completely destroyed the shipyards and the game has rebuilt them... but they do not work
)
