FTB Ultimate Server Crash

[Minatowolf]

Sorry if this is in the wrong section, this is my first time making a thread. Anyway, I just tried moving my world from my Yogcraft server to a FTB Ultimate server, and after a minute or so of being on there with my account, it crashes and I get this error report, http://pastebin.com/VFUT1A5h, if it helps at all, I was flying with my power armor suit and had long fall boots on. I would appreciate any help I could get. I have this server so me and my friends can play together. Also it's a Bukkit server with a few plugins, I think they are listed somewhere in the error report. Thank you in advance to anyone who can help.

I have no idea what causes this, but have you tried removing the block causing the problem with soem external program like MCedit? The coordinates are in the crash report (624,65,-242). If that doesn't help, reset the whole chunk it is on.

Okay, this is a weird one. It seems like a block of grass has glitched out xD. Try doing what moasseman said. If not, try killing all entities via the server console.

Yeah, I just pruned everything besides where we've built and it fixed it. How does a grass block glitch out XD, especially one I haven't gone near in forever.[DOUBLEPOST=1373419021][/DOUBLEPOST]Thanks for helping out, both of you.
