I'm having exactly the same problem but it goes further than a simple dialogue thing. Apparently it's a chapter problem and it keeps the story from unfolding after killing Mulahey. I've tested it a few time with powerful PCs in order to quickly clear the mines and my observations are:
- when entering into Nashkel, the game triggers the chapter 2.
- But then, strangely, every guard or commoner you talk to congratulates you for clearing the mines, even if you haven't done the job yeb. The game seems to consider you're alredy in chapter 3, since the dreams that come to you aren't supposed to happen before killing Mulahey.
- when you kill Mulahey and takes the scrolls in his treasure chest, chapter 3 doesn't trigger except if you set the chapter value with SK to 2 instead of 3 before taking the scrolls. But if you do so, Tranzig doesn't spawn and your journal doesn't update.
I'm basically stuck and the bug occurs every single game I start and I really don't understand why.
As for the mods I've intsalled, they are:
- Tutu tweaks
- Tutu GUI
- Murneth
- Finch
- Indira
- Tutu NPC project
- a few prestige class
