hello gap
to the 2, ähm i press the button with the weather, than it comes : wetterbericht gesendet. if i press the other button for the calculation of the position where the little stars in it , it comes the same sound. to point 3..... i guess it could be if the part of the ship is small enough that the software think it is "just" a bit more demage and so the unit is not dead or so.
