Any "place satellite around Mun" contracts, or around any other bodies but Kerbin, do not correctly check the body the satellite is orbiting. As a result, they can be completed simply by placing the satellite around Kerbin at the required apoapsis and periapsis.

Thanks a bunch for this. I looked into this issue and found the problem and fixed it. This helps me out a lot when people report these issues. Thanks. :)
