In most games, when I load a save, I expect to be taken back to the exact same conditions that existed when I made the save. In No Man’s Sky, that doesn’t happen.
It turns out that most of the environmental variables (time of day, weather, etc.) are independent of the save. If you make a save during the daytime, when the weather is fair, but you load the save at night, during a storm, you will find that your saved game is now at night, during a storm.
If you save during a fight, when you load the save, you will no longer be in a fight.
Handy in some circumstances, irritating in others - but definitely confusing.
