I'm not 100% sure if this is the right place to put it, but on this latest Tekkit build, I'm not able to pick up anything in the GalactiCraft Cargo Unloader, and can't even load a battery into it. Had no problems with the latest non-beta build though for that that I remember.
Has anyone messed around with the Energy Manipulation mod alongside the Tekkit mods? How did it work out for you compared to Equivalent Exchange? I've heard about it but really haven't had the chance to mess with it yet.
