“Don’t mine at night?” Who wrote this, a little poopy diaper shittin’ baby? Obviously it wasn’t someone as well educated on Minecraft as I. Mobs spawn when a chunk is loaded, which is when a player is in it. When the light level is 7 or lower, mobs spawn. During the day time, it is most likely the places where the light level is 7 or under will be in caves, aka where you go mining. In fact, mining at night is one of the safest places you can be, except, of course, for the safety of your own base. This is because mobs are spawning on BOTH the surface and in cave, meaning there will be less spawns in the caves where you are currently mining. “Don’t mine at night.” Psh
