A few of these are known bugs, such as the helmet hiding one (apparently it's connected to the wrong part of the armature) which will hopefully be fixed, and there's a few glitches with some of the clothing meshes where they flip up and get stuck there. With any luck they'll be fixed.
The facial feature one is a new one for me although I have seen something similar when panning around with the camera.
I've also experienced the problem with turns not ending as have a number of other people: it seems the main cause is a combination of elements, particularly rain and freezing if I recall correctly.
Hopefully these will be fixed quite soon.
The matter of Sebille's dialogue being obscured when eating things can apparently be worked around by placing the body part on the hotbar, closing the inventory and then eating it. Which I believe is Raze's idea, I'm not imaginative enough to think of that one!
