Upon loading a certain world, minecraft crashes, but not after showing me a frame or two of the actual world. I will refer to this as "the buggy world". This has not happened with any other world. Also, if I start another world or play an existing one for a while and then play the buggy world, I can have anywhere from 5-10 seconds of playtime. I will post a crash report as well.
*the world name is 1.7 Thaum survival*
