I have the same exact problem. My brother placed down a rotary macerator and then poof, server crashed. >_> Its really making me mad, especially since I read a bunch of other threads trying to fix it, but only accidently got rid of the most recent world for my server. This screwed up my server, and not only I am mad, I am furious. I made this server and played on it for 4 weeks, now I need to start all over until they fix this? Can someone please come out with a fix with this? I tried deleting the NetworkHelper and advancedmachines, but then it says it is missing... /: Tekkit really needs to fix this. I also now tried replacing it with a new download... Still didn't work.
