I am having a similar issue..
crash-report.txt

What was the fix?

This seems to be an issue caused by one of the loaded mixins rather than by Nature's Compass, since the method BiomeManager.getBiome isn't meant to throw an IllegalStateException. I may fix it in the next release, however I'm also interested if @Phweeeee figured out what was causing it.
