Birthright won’t trigger

I’ve been replaying Dragon Age II and I’m nearly to the end of act one. I went to Gamlen’s house and triggered the conversation between him and Leandra about the estate and then spoke to Carter about it, he says let’s go, but the quest isn’t showing in my journal or on my map regardless of it being night or day and going to darktown changes nothing. I’ve also gone back to old saves to try to trigger it earlier with no luck. I’m playing on pc and wondered if anyone else has experienced this.
