I read on Reddit that the disappearing sword happens when a cursed thrall explodes over it...not sure if true or not.
Not specific to thrall explosions, but I've seen some correlation between nearby explosions and the sword disappearing. I've also seen many, many times where the sword is sitting all by its lonesome, not a care in the world until.... whoops! Fell through the floor. Not dictated by time either because there have been many times when it sat around much longer than times when it disappeared.
I think there can be some correlations (same as the insta-kill fast stand up) but I haven't been able to identify any absolute rules. So hooray for that.
