Yes, I hope the Elminster responses fixed to! The other companions apparently do have comments for Gale Origin, but people have only found them in parsed dialogue. Hopefully it's an easy fix.
A friend of mine looked into it with the script extender and apparently the flags are a bit odd. I hope it gets fixed because apart from Lae'zel's (my bro, my besti, my confidant) encouragement, Astarion's little speech about personal will opposed to that of the gods is a highlight.
I hope I don't try our dear mod's patience by adding that I don't want an epilogue kiss for Spawn Astarion. I really like that he has a hug instead. It's both a throw-back to his act 2 scene and evolution of it. Where the act 2 hug was stiff, the epilogue hug is one of two people being extremely comfortable with each other.
