Glad to have helped
This game always seems to have something new to discover. I only realised on my most recent playthrough that I could actually get out of the Shattered Sanctum through a hole by following Liam when freed from the torture rack: I always thought that he just magically vanished in the way NPCs exiting the stage seem to do!
It sounds as though possibly the Paralysed status might have been preventing the Knocked Down status expiring, and the Knocked Down status was preventing Pandirna's dialogue triggering. Which, as you say, is still a bug but feasibly an edge case that hadn't been tested.
