My workaround sucks. I forgot I can't use DestroyObject if object is dead.
 Anyway, I was trying to use different anim... I found a way!
 AssignCommand(oVisas, ActionPlayAnimation(10083, 1.0, (-1.0)));
 Using this in very last node of conversation works just fine :) There's another problem though, she's "dead" but her lightsabers don't know about it...

 I will try to unequip her weapon, hopefully it'll fix that problem. 
 Anyway, thanks for the help (both of you) :) 
 You could try adding a line before the animation of 
 AssignCommand(oVisas, SetLightsaberpowered(false)); I think this is it, not positive but there is a script command for setting a light saber on or off. 
 oops to slow! go with swfan's its right.
