Crashes w/ the Oh, the Biomes You'll Go Mod on game load
Crash Log

ok so, this is 100% the other mod's fault, so the offending lines mentioned, according to a decompiled class is:
GameRegistry.addSmelting(Blocks.field_150350_a, new ItemStack(block), 1.0F);
that is a line in their mod, that translates to Blocks.AIR
they are doing some weird thing, not our fault, nothing We can do.

Ok, thanks, and I believe it was made using MCreator
I'll let the mod author know
