A member of my clan was kidnapped (Drydon). I killed the kidnapper monster but the quest did not complete and Drydon was still listed as kidnapped. Drydon had been a part of my previous hunting party. When I sent out a new hunting party, Drydon's name was still highlighted and could not be unhighlighted. When I sent the hunting party out, Drydon's health bar appeared along with the others in the party. When the hunting party came back, Drydon was in town, with a green exclamation point over him. Clicking on him gave me the option to rescue him, which I did. That is when Drydon became freed from kidnapping, and the kidnap quest was solved.
