Long time no post ... just getting back into Baldur's Gate 2 (you lured me back with prospect of playing the Mazzy friendship, I was WoW bound, but that will have to wait a little longer now).
Unfortunately I appear to be experiencing the same problem as Wisp (and Cal) ... I posted at G3 earlier, because at that time I had no idea which of my mods was causing it.
Also whilst trolling around de'Arnise Keep Minsc suddenly piped up with
"Ah little Imoen is growing up .... last saw you". I'm presuming that this should have happened at some point prior to the little witches kidnap, or post rescue?
Raven_Song: Interesting idea - could you give us some more examples of what you're thinking? Maybe a banter sketch? There's a "rash" one already done, with Aerie and Minsc.
Sorry I've been ill recently so haven't had much time to think about gaming ... give me a few days and I'll see what I can come up with.
