The ability to leave and continue continue the next day from where you left (aka 'saving your game') is called 'persistence tech' in SC and is currently in 'tier0'.
It's what's so irritating about the project. They proudly brag of half-baked implementations of basic functionality that every other studio silently takes care of in the first few months of Pre-Alpha development, give it a fancy name and loudly proclaim they are revolutionising the entire industry.
In this case it's particularly bad: go trading. You buy cargo to sell elsewhere, the game crashes, you lose your cargo. It means that if the game crashes once every ~25 runs you will run a loss overall. It's not even close to a top25 issue, but this alone would have people ragequit permanently in any other game.
It takes some time and perspective to really grasp how mind blowingly poor it is, and how absurdly incompetent a studio has to be to deliver this after a decade and 400 million dollar. It's unquestionably the single largest failure in the industry, ever.
