I want to run this. Just have questions.

There are 2x48 exosuit slots, one is called general the other is called cargo. Upgrade both or just the general exosuit slots?

About the EXTREME SURVIVAL milestone. This requires you to stay on an extreme planet without entering your ship for 8 hours and needs to be done in one session. I plan on sleeping and letting my character inside a base doing nothing, game and timer keeps going. If my pc crashes and Livesplit resets at that point, can the timer also be considered,

(last save time when finally reaching center and fulfilling all category rules-first save time)?

The game makes the first save on it's own when you create a new game. I run it on steam-pc. It crashed while i was sleeping, 20 hours into the game that is why i ask about the game save timer. I will probably do the artemis-apollo-null questline too, feels more complete.
