Sadly 2.3 doesn't seem to like any ore that is has in common with RP2 anymore. Can't get Tin or Copper from either RP2 or IC2 to macerate. Please add support for the Ore dictionary when you get a chance
I'm also getting the error with Rei's minimap v2.6 when adding in this mod. I have IC, BC, Rp2 and a couple other mods installed, including some of the authors other mods and they all play nice together. Only when I add the advanced generators does it throw the error and goes back to normal when I remove it.
