hello, if I’m trying a speedrun like all advancements (im really bad btw), that takes a long time, could i leave the world, pause the timer, and reopen the world on a new day? how does it work if i leave the game?

also i was gonna specifically try set seed all advancements

You can actually do All Advancements speedruns in several segments, as long as you're able to provide the full footage, and set up and ingame timer so you know exactly how much time you've spent in that world

Meaning you can't turn off your computer overnight ^^

@gravefruit what? yes you are allowed to turn off your computer...
