Bump... brand new game as of this patch, Madora again breaks dialogue chain, this time in Arthu's study after going through typical NPCinteraction. One thing I noticed: I didn't get credit for choosing sides until I exited the area, down to barracks, at which point my characters updated with floaties giving each a +1 in whatever they'd chosen upstairs (altruisim and smething else).
Madora still had a "!" floatie, but when I spoke to her I got her normal dialgue... and then I exited the area, tried talking to her and got nothing, unresponsive again, no dismiss option or anything.
I'm thinking there has to be an issue with location transitions that is messing with the memory or the save state.
