I am with you about the Spawn's bit. I was kinda hoping they would fix those kiss lines in this patch but they didn't. It may seem a trifle but I really wouldn't mind hearing them in my Spawn route.
I know there's a mod supposedly fixing them but why rely on that. I wonder why the lines are not triggering, is this a bug or something else. I don't think they would contradict anything in the story when they play out later on after the ritual.
