This crash happened as soon as I placed a Tinker's Construct casting table below a Centrifuge that was set to auto output to that side. I didn't have time to place the ingot cast before the server crashed. The world now crashes on startup. Sorry if this is an older version, but it's what is in the FTB Unstable pack.

What Version of NeoTech are you using:
NeoTech-1.8.9-2.4.1 (from ftb-unstable)

If possible, did you break and replace the block:
No, the server crashes on startup

Please Pastebin.com the crash Report and put link here:

Fixed with last push

You guys are trying to fill with a null. You shouldn't do that.

Crash log says the crash is coming from tinkers.

My bad, we are updating to capabilities anyway so I'll go through and clear those out
