I just finished the TIE Fighter Tour of Duty campaign (Collector's CD version) and decided to play some of the ship-based introductory missions (backwards, I know). When I select a mission in the combat chamber-say, TIE Interceptor mission 2-it plays fine, but as soon as I complete the primary objective(s), the mission just ends. Most of the missions have secondary/bonus objectives, including ones that by design can't be cleared until completing the primary objectives. However, since the mission ends when the primary goals are achieved, I can't actually do any of them. The tour of duty missions didn't have this problem.

I've tried several different missions with different craft, and they all do the same thing. Am I missing a setting somewhere that causes this behavior?
