I'm playing Battle 2 Mission 3, and I'm running into a problem. The goal is to defeat all Y-Wings and hostile shuttles in order to defend a patrol craft which will then dock with a nearby Star Destroyer. I knock out all of the hostiles, but the patrol craft just sits there. I've tried this a couple of times, and made sure that the patrol craft's escorts are still alive. I also inspected all remaining craft.

Still, nothing happens. Any ideas? Is this a bug, or did I miss something?

there are already two threads about this
