Silinde Ar-Feiniel

Install: tactics

Action: After saving Riatvin from demons, a cutscene occurs, the screen turns black and there goes the transition from "Riatvin with demons" to normal Riatvin. After some seconds, there is a CTD.

Error: ASSERTION FAILED!

I went ahead and tried out some "trial and error" thingys and I found that:

If I Ctrl-Y Shandrah, the crush never happens.

If Shandrah is alive the crush happens no matter what area I'm in. I even tried traveling to the temple and res her from there, but after that, within some seconds the crush occurs.

Also, even if she has no items at all, the crush occurs.

Could it be a script?

I would really appreciate your help!

Install: tactics

Action: After I tell Belt that I'm ready to go, he wishes me good luck and then the screen goes black for a few seconds. A cutscene begins, in which the party stands in the south-west corner of the map. The characters are killed (except Sandrah who is removed from party but is alive) and Imoen, Minsc and my main char appear again revived with no items in the middle of the map. Then, Imoen and  Minsc are removed from party, a cutscene begins and then the screen goes black for a few seconds and then the CTD occurs.

Characters:  protagonist, Imoen, Jaheira, Minsc, Sandrah
