Problem Infamy server keeps crashing

[fakecheez726]

So recently I made an infamy server from scratch, since it isn't for download, I copied all of the mods, coremods and the config from the Infamy file. The server runs 1.5.2 which is the infamy version, I made the server with Forge 1.5.2 so thats not the problem. So to the point when I open the server it crashes, heres what I get in the console.

I think you have a client side only mod on your server. Inventory tweets or zan's minimap maybe?

the crash report in pastebin would be more helpful as I could see a list of the mods your trying to install with versions.
