Keep getting a error:

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Mekanism (mekanism)
Caused by: java.lang.ClassCastException: net.darkhax.bookshelf.lib.ModTrackingList cannot be cast to java.util.ArrayList
at mekanism.common.util.MekanismUtils.findMatchingRecipe(MekanismUtils.java:1354)

I added mods that utilize the bookshelf and i keep getting this error. If i disable them then mekanism loads fine along with the other mods

Duplicate of mekanism/Mekanism#4414 Issue is in Mekanism.
