I dont remember the patch notes so good, but I think I have read something like this during the year:
- Fixed hunters fading through walls, and teleporting into bunkers.
- Fixed flashette weapon not sticking to the character.
- Fixed sounds from dead robots.
All of the above has started re-occuring on my system.
(Flashette never stopped but I thought it was intentional that the flashette weapon stuck into your skin and exploded.)
