This mod makes it so whenever criteria is met for an advancement, the game will save the world.
This ties in really well with AATool, as with this mod you don't have to pause for it to update.
This is also really useful for Coop runs, because in Coop the player data only gets saved every 5 minutes.
I've made it so that it waits 1 second
after getting the first call of a criterion being met, and then saves. This is to avoid lag.
