Kerbal Space Program

I had a contract to rescue a Kerbal and to bring his wreck back to Kerbin. I used an Engineer to make his pod (which was a "Pea" reentry module) part of one of my ships, and then brought it back to Kerbin. I got credit for rescuing the Kerbal, but it still thinks that I did not successfully bring back the wreck, even though the part survived. I'm assuming I had to have the part attached with Docking ports or an AGU for it to have been successful, but since Engineers can attach parts directly now, that should also be allowed. Since I've already recovered the part, there is no way to now complete the contract.
