Hey I am new to this game, If I log out half way through a mission, when I log back in, will I be half way through it still, or does my ship vanish or does it remain and get destroyed? even when I log out?
if you say get to the ground part and log out, then at any time you can log back in (you will be dumped back into sector space for example) but you can go straight to the ground section of the mission although you have to start from the beginning of the ground section.
if you log out and back in quickly then you should be ok and wont lose any progress with the ground section. if you wait a few minutes then it will reset back to the beginning.
