LegacyCraft Mod 1.7.10 is designed to allow the ability to roll back pieces of the last few updates to Minecraft which have a tendency to force the game in undesired directions, or which make the game more difficult than is enjoyable for casual players. Each option can be configured individually. Note that disabling the new AI overrides the other AI-type changes like zombies targeting villagers.
