I've noticed that you can fit multiple Auto Field Maintenance units onto a ship. Does anyone know if they stack or by fitting two do you get twice as much 'maintenance' out of them (ie do they last twice as long)?
Sadly I can't answer your question as I haven't used them yet, myself - I'm actually curious how they work as well. Is it really automatic, or do we have to trigger it like a shield cell? What kind of damage does/doesn't it repair? I heard people saying that thrusters and FSD can't be repaired, so what do they do? Just repair general hull integrity?
