I added this mod to All the Mods Lite (latest version) and, after disabling railcraft, began pregenerating the world. Saved and quit last night, came home from work today and restarted it and it crashed after ~10 seconds. Had a similar issue on another pack with a different mod.

Here is the crash report: http://pastebin.com/QEGT9j9j

Has been reported and fixed (#718)
