I have created successfuly created a book. When I open it on SSP everything is fine and works perfectly. But when I try to open it on the Server, it crashes server completely with following Crash-log: http://pastebin.com/QsXWxJg3

If needed here are the config and json file used: https://github.com/JasonMcRay/InfiTech-1.7/tree/dev/config/enchiridion

Both server and client has exactly same config and book json file.
