voltz is calclavia's modpack...
And the developer of Mekanism and calclavia don't have the same oppinion of how should everything go on...Haven't you realise yet that mekanism isn't anymore enven on the u.e web site?
And now they can't even work toagather.
But I still don't understand why they can't put the Mekanismback in? They needn't work togather, the mods just have to be compatible
