I was using the centrifuge, and it only had lava in the output, all other fluid tanks were empty. I had put in a structural upgrade, and there was a wooden buildcraft pipe on the right side of the machine (An item pipe, not the fluid version, it was being used for something else), and when I set the centrifuge to output on the right side, where the pipe was, the server I was on (I was the host) crashed. Now, whenever I try to start the server, it crashes, even before anyone gets on. Which means I am unable to use /setblock to turn the offending centrifuge into an air block or something like that.

What Version of NeoTech are you using: 1.8.9-2.4.1

If possible, did you break and replace the block: I was unable to rejoin the world without it crashing, so no.

Please Pastebin.com the crash Report and put link here: http://pastebin.com/4MV3FbEJ
