I need to copy my base with a mine from the old world to a new one (the seed and base coords will be the same). Can MCEdit copy IC ores and blocks to a new world, can he inadvertantly remove IC ores from the schematic or remove IC ores from a new world? I just had a most unpleasant experience when I mistakenly entered my IC world in a configuration without any mods and Minecraft deleted nearly all IC ore from the world.
