Dynaheir may do this if your rep is too low.  Otherwise, BG1NPC should catch all the potential leaving dialogs and change them so the person will not leave.

No, no, this is a known BGT-WeiDU problem and has been reported by KD and also fixed by myself.

Ascension64, do you mean it is fixed for a forthcoming version of BGT-WeiDU zeta or a future tweakpack?

Thanks

Music and NPC banter are what make BG so good and gives it such a high replayability factor, so I'm all for it.

Minsc suddenly started a dialogue with Imoen in which he talked about how good it was to have her back in the party. Irenicus is mentioned and Imoen talks about the death of Khalid and Dynaheir so it is all very BGII.

Is this a known bug? BGT-WeiDU related or something else?

What else did you have installed again?  Contents of WeiDU.log would suffice.

WeiDU.log attached. I have not installed anything new since I first started the game. I tried to recreate the Minsc/Imoen problem but did not get it so it might have been a one-off glitch.

I now have Dynaheir in the party, but a new problem is that every time I try to initiate a conversation with her she says her departure dialogue (something along the line of "nice knowing you... see you later... goodbye") and takes Minsc with her. The dialogue then immediately repeats itself and if spoken to again she and Minsc rejoin the party.

Erm, well, both BGT Tweak pack and BG1NPCBGT attempt to 'complete' the Kagain quest.  I wouldn't install the 'Finishable Kagain caravan' quest component if you intended to use BG1NPCBGT.

I think the dropping Monty/Xzar thing is just a coincidence; someone's banter time probably ran out just after you dropped him.  If you don't drop Monty/Xzar and wait say for an hour, does a banter start?

Problem sorted... I uninstalled the "Finishable Kagain caravan quest" component and that worked. Dropping Monty/Xzar doesn't trigger any dialogue or banter (I've waited several hours) and Kagain's quest seems to conclude with him saying he's had enough of searching for the caravan.

Glancing at your install list, I noticed you have both the BG1NPC project and the following components from BGTTWEAK:

~SETUP-BGTTWEAK.TP2~ #0 #0 // Eldoth reminds of Skie's ransom
~SETUP-BGTTWEAK.TP2~ #0 #1 // Angelo notices Shar-teel
~SETUP-BGTTWEAK.TP2~ #0 #2 // Finishable Kagain caravan quest

BG1NPC features its own versions of these (well, definitely of the second two, and I'm pretty sure of the first as well), and two or more mods trying to do exactly the same thing often leads to trouble.  It doesn't always cause problems though, but I just thought I'd warn you of the possibility.

Thanks for letting me know... I was not aware of that. The Kagain quest did not work for me so this is probably why... I'll re-run BGTTWEAK and uninstall those 3 components.
