No Peaceful Despawn
Keeps monsters in Peaceful Mode with gamerule tweaks.
About this Mod
Have you ever switched difficulty to peaceful by mistake? If you have, then you know that suddenly ALL hostile mobs are gone! Iron farms are broken, your xp grinder is missing an endermite, and that one endermen that's been piling dirt around itself in a boat seems to have teleported away, and worst of all... that zombie that picked up your best netherite sword is all gone!
That's what this mod is for! Turning on peaceful mode won't make mobs despawn, but they still will stop spawning [pst, hey! you can turn on monster spawners or infested blocks with /gamerule doPeacefulMobSpawners].
