So I've been playing on this modpack for quite a while, probably 10-15 hours put into it, and then one time I go to start up the pack and when I try to enter the world, it crashes.
Crashlog -> http://pastebin.com/z2hPJZw6
It says that there's an exception getting block type in world, but I'm not sure what block that is, nor how to fix it.
Thanks in advance to anyone who might take a look at this and it would be much appreciated if you could help try to fix it.
