Problem orbital probe contract

Question

I have a contract to put a satellite into an equatorial orbit of Kerbin. I have a rocket on the pad ready to go, but when I go into either the Tracking Station or map mode, the contracted orbit is not showing up. I at first thought that it was because the argument of periapsis is "NaN" while the orbit is not circular, so I made one up and put it in (270 degrees, because why not?), but I'm still not seeing the orbit.

Here is the contract:

                                        values = 0,0,0,0,0
                                        holdSeconds = 10
                                }
                        }

Any one have any insight as to why the orbit lines for this orbit are not showing up in the Tracking Station or Map mode? 

Thanks!

Known bug. When any of the contract orbit parameters are either N/A or NaN the orbit lines will not be drawn.

Forgive the mundane adage, but have you tried restarting the client? it may just be a memory bug.

Oh yes, I have. I did all that long before I dug into the persistence file.

Ah, that would explain that then. Thank you.

i guess the game can't show a target orbit when there is an infinite number of valid orbits to fulfill the contract? frankly, those contracts should not be generated at all. i guess they are supposed to be easier than a strict, fully defined target orbit, but in reality they just create confusion because there is no target orbit on the map.

Nobody said yet on this thread, but putting the satellite in any old orbit with 0 inclination and the correct Ap and Pe will fulfill the contract successfully.

I like this "new kind of satellite contract" as a concept, but the contract should be reworded to say something like, "Put a satellite in any equatorial orbit with specified Pe and Ap altitudes". Then people would understand why the lines weren't being drawn. But do make sure that you pay some attention to the second half of my bug report there -- check the sizes on your KSP.log and output_log.txt files, because sometimes they balloon.
