+- 1.31- Added 'attack_animals' and 'specific_attack' flags for custom monster attacks, also 'mob_difficulty' .conf setting to make mobs harder.
 - 1.30- Added support for invisibility mod (mobs cant attack what they cant see), tweaked and tidied code
 - 1.29- Split original Mobs Redo into a modpack to make it easier to disable mob sets (animal, monster, npc) or simply use the Api itself for your own mod
 - 1.28- New damage system added with ability for mob to be immune to weapons or healed by them :)
