I keep getting a crash on SSP when loading into a new world. I don't have any other pre-existing worlds on this pack to load into, so I can't test that. The full log is in the dropbox link, as it won't fit on any pasting sites or in this box.
https://www.dropbox.com/s/95dmdtqgnsc6flb/fml-client-latest.log?dl=0

Here's the truncated log, too.
