Kerbal Space Program

I just got my first probe into solar orbit in a new game started under 1.0.5, and after I switched to a new launch, I noticed I had gotten a world record for escaping the sun's gravity. I checked back and my probe is still happily in solar orbit, slightly offset from Kerbin's, so I can't see anything I did to trigger this event.

Here's the relevant fragment of my save file:

Sun
            {
                reached = 269823.649643943
                Orbit
                {
                    completedUnmanned = 269824.649643943
                    vessel
                    {
                        name = Test
                        flag = Squad/Flags/hexagonCircles
                    }
                }
                Escape
                {
                    completedUnmanned = 270087.351987799
                }
                Science
                {
                    completedUnmanned = 269995.105464304
                    vessel
                    {
                        name = Test
                        flag = Squad/Flags/hexagonCircles
                    }
                }
                Flyby
                {
                    completedUnmanned = 269823.649643943
                }
            }

The probe, the only thing that's ever even gone outside the Mun's orbit, doesn't show that in its trip logger, though.

Log
                    {
                        flight = 0
                        0 = Flight,Kerbin
                        0 = Suborbit,Kerbin
                        0 = Escape,Kerbin
                        0 = Flyby,Sun
                        0 = Orbit,Sun
                    }

So I don't know what the game thinks escaped the sun's gravity, but it wasn't anything of mine...
