In the past few days I completed the chapter 3 class quests on my Jedi Knight and Imperial Agent. I got credit and it shows on the character selection page and my legacy window. Tonight I finished the Trooper's chapter3 class quest line and didn't get credit for it. On my character selection page the trooper icon is still shaded out and beneath it still shows 7/8 finished. It also did not grant the Trooper heroic ability, that still has the lock showing.
