I was in the middle of something so I didn't get a save or anything, but I had just finished rescuing my villains childhood teacher (I believe I had picked "I need even more money" for my plot option previously) and when I went to talk to the quest giver the chat window said "Thanks, now I know more about *villain's motivation." but I also got a couple of ASL language unknown errors IfChatNPCVillainous and IfChatNPCheroic.
Most of the time when I've seen errors like that pop up it's because of an unclosed tag, or an extra character between the argument and the things to be checked, sorry I can't be more exact about where I was, though.
ETA: This probably should have gone in the bug report thread, sorry about that. Now that I've found it, I'll stick to that.
