I don't know whether this is a bug (probably is) but for some reason I can't get arrested in Candlekeep having killed the Iron Throne stooges, and if I elect to go talk to Tethoril/Ulraunt instead nothing happens. Is this related to an earlier experience of having killed the Tan'nari (or whatever it's called) in Ulgoth's Beard and then receiving the experience points for the kill over and over again like it was in some loop. Also the movie as I enter Candlekeep loops over and over again until I reach the stairs going up. Are these related, and does this mean I'd have to restart sometime before killing Mr. Demon??

That arrested event happens after a certain amount of time after you enter Candlekeep. Ofcourse if you've been there for ages and nothings happening then something's very wrong. You might have to use a save from an earlier point or something.

I think there is a cheat to skip episodes. You don't miss much, as the rest of episode 6 is sh*t

You miss two stat advances (tomes) in the cellar. I wouldn't skip.
