A Bukkit plugin that gets brings mobs closer to players
We've changed the original implementation removing some stuff and added a 'real feel' to the plugin by using this PR on spigot: SpigotMC/Spigot-Server#71 So keep in mind that you'll need to compile your own Spigot before using this - until the PR may be accepted.
This change enables real mob ages, even after server restarts.
