I have this issue as well, with no biome mods installed.

can you try without chickenbones mods or optifine? both still in the log

It's a random crash. I've deleted CodeChickenLib a few hours ago and crashed again, now the crash looks like the first one (the one in the issue topic). It's probably a conflict with OptiFine.

Can you reproduce this with only quark?

No. It appears to be some kind of conflict with mods that add other biomes.
