Title: 0.5.4 Crash on Server Start

Version: 0.5.1

OS: Win7

Java Version: JRE7V11

Appears to be specific to my server's world. Forcing the server to create a new world works fine.

Edit: Updating Buildcraft does NOT fix this issue, nor does removing it temporarily.

Update: I was receiving this same error with 0.5.5 as well. I removed the offending pipe (attached to an MFSU to serve as a sensor). I then began receiving Logistics Pipes errors of the same type. These I fixed by manually updating Logistics Pipes.
