There was a cutscene about Nightsong lifting the Shadow Curse after being freed. But it's not gone. Nothing changed.
Before that, I was making progress with Lift the Shadow Curse quest with Halsin. It's apparently also now stuck forever because I killed Oliver. (He was a blighted abomination. I've noticed the game often does not recognize a good aligned character's urge to destroy evil corrupted or undead creatures, or at least acknowledge them in dialogue. The House of Healing - you have to talk to the undead nurse as if she's a normal living human. The corrupted Innkeeper - Gale casually goes to order a drink as if it was completely normal)
Before that, Isobel was kidnapped and her protection was removed, if that's somehow connected. But the game isn't recognizing anything, the quest is just stuck.
