Hello, My server keeps crashing when I try to run it. Clearly I'm missing a mod, but what's confusing me is that the client works fine. Yes, I do have codechickencore, COFHcore, and probably some others I'm forgetting. Anyway, here's the crash log:

Hello, this is my first time on the Forge Forums, and I hope this attempt to solve my server crashing proves fruitful. My friends and I put together 60 of our favorite mods and want to play on a server with them. (We've done this successfully before with about 40 or so mods.) However, this time the server crashes once I add around 10 mods to it. I can sometimes figure out what a crash report says, and what's wrong, but this one is quite long. The most confusing part about it is that the same mods run fine on the client. And I have checked 10 times to make absolutely sure that no client side mods are in the server mods folder (Besides NEI and ChickenCore of course). It seems like the problem is not specific to any one mod, but something more general. Any help would be GREATLY appreciated. My friends and I really want to get back into modded minecraft. Thanks in advance. (crash log is in the spoiler below)
