I keep getting this error at random times, when i open the arcane terminal.
http://pastebin.com/rSaVZ9eV It crashes the server completely.

According to the stack trace:
"
at appeng.me.storage.MEMonitorIInventory.onTick(MEMonitorIInventory.java:234)
at appeng.parts.misc.PartStorageBus.tickingRequest(PartStorageBus.java:409)
"
There is an issue with a storage bus somewhere on the network. The ME network is trying to update it's internal storage cache and crashing when the storage bus is reached.
You may want to let Algo know about this.

Okay, i will let him know. :)
