Well as the Title says it is not working as a carbon source.
Setup is fine as we tried wood/coal and it is working fine.

generators-0.9.18.113-mc1.7.10
Mekanism-1.7.10-8.1.7.252

No idea why that stopped working, but switching the default configs to use the item directly instead of oredict seems to fixed. Will be in next alpha build.
