Link to crash log: (please use a paste site such as gist, do not attach the .txt or paste the log inline)
Steps to reproduce:

1. Place Life Imbuer (y 68) on a Zombie Spawner (y 67) (underground, base is at y 76)
2. Place mana pool (y 69) and mana/gaia spreader (y 69)
3. Connect spreader to life imbuer with wand of the forest

What I expected to happen: Zombies will spawn, even when I am not in the neighbourhood or even offline.

What happened instead: No mobs are spawning when I am 1 chunk further from the spawner. Chunks are loaded, Rotten flesh is connected to corporea network so I can watch through the Crystal Cube, but the loot is not adding up when I am not near the Life Imbuer.
