Late but i had the same thing.

Solution is to download and use NearInfinity go into the CRE folder to tanar.cre then in edit tab scroll until animation and change it.

Thank you, I recently played again after modding the game and completly forgot about the bug and the fix for it, so I had to rediscover it once more.

the EEKeeper savegame editor allows you to alter that particular file aswell.
What you have to change is (Copy pasta from a forum post)
EDIT: This has been fixed by changing the animation of tanar.cre from fiend_green to tanarri.

1) Install the EEKeeper
2) Open the tanar.cre with it
3) change the animation to tanarri (simple drop down menue).
4) Save
5) Enjoy the game.

Thank you for your reply, I completly forgot about this post and that I probably should have posted the solution I found back when :) (which seems to be the same you found just by slightly different means)

You are a life saver.

Hi,
I am experiencing a repeated game crash during the final fight of the sword coast expension in Shandalars basement. When ever the spawn animation of the demon nears its end the game freezes up and crashes.
Google provided me with a potential fix

sadly no instructions on how to do this and I can't seem to find any such file.

Could someone point me in the right direction (or explain an alternative fix)?

Wow, he really has demonic powers after all O:

maybe its not just a game if he can make the users PC crash with magic to save himself.
