Keep Peaceful Enemies Port

This mod addresses one specific but important issue in Minecraft. When you name a hostile mob and switch to peaceful game mode, such mobs typically disappear. This modification prevents that - named hostile entities remain in the world even in peaceful mode.

The functionality here is extremely simple and straightforward: nothing superfluous, only protection for your named creatures from vanishing when changing difficulty modes.

The mod icon uses the Digs' Simple Pack resource pack, which is definitely worth checking out - it's executed with taste and simplicity.
