The 10 to 20 block thing is a major help to be honest as I find loot resets can cause it such as trash, cars, boxes and so on which reset every so many set days via user settings
Ive noticed if you are atleast 20 blocks from any building and restart the game once per in-game day I do 20:00 in-game time that crashes are far in between if at all and if you wipe the local save you lose nothing after a crash.
Ive tested this fully on a 200+ day save with no loss at all...
Crashes and delayed updates
What would be a fantastic thing is to fix the crashes that result in the bleeping deletion of half your base... Just saying I'd forego new content just to have a playable game where I don't lose my stuff in single player
