How to fix the Rotary Macerator Crash?

So my server crashes as soon as I start it up, I believe it to be the rotary macerator bug that many people have experienced. I found a guide on how to fix it here: http://forum.feed-the-beast.com/thr...ception-nullpointerexception.5531/#post-70511

I've gotten stuck on the NBTExplorer step, when I open the chunk that the coordinates tool led me to it doesn't list any tile entities, does anyone have any other ideas about what is going wrong or how I can fix it?

Fixed it by just disabling advanced machines, would still be curious to know why the other method didn't work.
