Fare well for now, friend. I will keep your efforts in mind when I become a benevolent Lord of Murder. However that works.

This tale might give you insight into the cause of this particular quest line crashing. I'm still on the last quest of TDD and I encountered the Weslun Tane character who turns into an acid elemental and is supposed to possess people. I read in this 8 year old guide:

Baldurs Gate 2: Shadows of Amn mod: The Darkest Day Walkthrough v. 3.0 017/03/02 by Suburban Jub Collective
"you need to attack the guy who has been possessed almost to the point of death and then Weslun Tane will reappear on his dais"

I found that even after beating someone to 1 hp and walking away for 1/2 hour while a mage tries to melee a regenerating character to death, possession does not time out. Killing a possessed character spawns another invincible elemental Tane that possesses another character you must kill. When you run out of every character besides yourself, you can finally kill it, but if you stay in the area the game crashes pretty soon. Windows recognizes that the game has crashed and minimizes pretty instantly. I got around this by just having my main character in the building, killing the acid elemental only once, and leaving the building quickly.

This is the weslun tane creature. Edit: found the acid elemental.cre but don't know if this is the specific dude spawned for the quest.

Hope these guys help. Also good directions, only took me a couple seconds after reading your post.

Whatever the problem is, I don't think it lies with any TDD file. It's either a random error, something to do with the infamous geforce 8600GT I have, or most likely that alot of things don't work if you install BWP without BGT and bgt dependent mods.

I started bg2 with a 6 person level 7 party, fighting mod implemented 20+ level mages with the following spells completely broken: Spell thrust, Secret Word, Pierce shield, and ruby ray of reversal. I also found that the new spell immunities are only removed with khelben's warding whip. Spell strike (9) and Mystra's unraveling (priest 7) remove everything except for spell immunities. Try getting a mage out of invisibility so you can target it with spells when it has immunity divination and immunity abjuration up (including spell trap, absolute immunity, stone skin, prot. magical energy, prot. elements, fireshields, and the new level 8 version of globe of immunity so it can't be aoe'd.) I had to drag around Jan janson with his stupid detect illusion goggles for 8 levels for god's sake.

Anyway my point is that this avoidable cut scene crash isn't the worst turnip I've had.

I didn't find ddvoice.cre in my TDD folder. I searched and found 3 copies(?) in 1. BGII - SoA\aurora\backup\0, 2. BGII - SoA\generalized_biffing\prod\0\biffs\31, and 3. BGII - SoA\xpmod\backup\0

Which one is bg2 using in game, which is an original? My only clue is that BGII - SoA\xpmod\backup\0 was "last modified" 10 minutes before the others on what I presume was the date I ran BWP setup.
