First off I will say that I'm using CoFHCore-[1.7.10]3.0.0B6-32 and Mekanism build 136.
I NEED to use this version of the CoFH API in CoFHCoreB6-32, because I can only use a certain build of forge.
If it's the version of CoFHCore that is the problem, then what MEKANISM build can I use with CoFHCoreB6-32?

This issue is probably related to #1994 #1998 #1999

@Erycus Mekanism already updated to new CofH Energy API. So if you can't update CofH ... you need to downgrade Mekanism.

Or maybe ...have you tried installing CofHLib?

Well I'm beyond embarrassed.

Seems I forgot CoFHLib
