Error Log:

dont quite understand what error log is...but im guessing this Slot 241 is already occupied by codechicken.enderstorage.BlockEnderChest@42e407bb when adding ic2.common.BlockRubSapling@8b7a84c is the problem and i dont know how to fix it. ive already tried several things already named above.
