Issue Description:

client keep on crashing

What happens:

I have some magical crop farm with farming station going into a chest which eventually gets full pretty fast. so I set up some automated essences into corresponding ores which are fed into storage drawer from storage drawers. After I finished building it with energy conduit and item conduit, the game started to crash at random times, which sometimes it takes less then 5 min for client to crash while one time it can be 15 min.

P.S: I have just added cobalt seeds and essence into the system and immediately game crashed. maybe that is why?

P.S 2: I have just activated the one for lapis lazuli seeds and also crashed the game while gold seeds nor diamond seeds did not

What you expected to happen:

possibly problems with energy conduit going into storage drawers?

Steps to reproduce:

1. chest feeding items into storage drawers and crafter from enderio
   2.connect the system with enderio energy conduit and item conduit
