Henchmen running off into mountains - standing around = failure of quest completion

This is a rather serious glitch/bug which has ultimately made me waste my time in the game.

I'm about to finish a quest, when a henchmen runs off into oblivion in the middle of a mountain, I die, and another henchment just stands there (ranger) without doing anything else. Grid lock.

Rinse and repeat. Is this problem being looked after?

I would hope so, as there have been quite a few threads about this problem. I've experienced it a few times myself, and it must have cost me an hour or two.

are you talking about a henchman getting stuck in the ground? because i had a henchman (little thom) fall into the ground and then when we all died he was just standing there in the middle of the earth, so i had to restart the mission. i think i even took a screenshot of it.

No im talking about a henchmen floating in the sky and running INTO a mountain.
