Yeah, that's an OPM thing. The latest version has the same problem. I'm not particularly planning to make another 10x config for 1.3. It's not super hard, though -- go into RSS/realsolarsystem.cfg and delete the eeloo section, go to kopernicus/config/system.cfg and increase radius and semiMajorAxis of the planets and moons it adds/modifies by a factor of 10, mass by 100, and rotationPeriod by, say, 3.14; and go to kittopiaspace/saveload/*.cfg and put an extra zero on the outerradius and innerradius values. If you find that planets' orbital velocities are too high, reduce the sun's mass by a factor of 10 in realsolarsystem.cfg.
