Not sure if this has been fixed in game yet as I've been messing around in dev kit the last few game patches. However, it seems the issue related to the mens faces disappearing when they put on the pirate/hide pants is related to the wrong texture being plugged in to the material instance. I stumbled upon the issue while attempting to convert all the armor to skins because there are a few with very similar names but when the correct texture is plugged in, the gaping hole in the mesh of the mans face was fixed.
Hopefully this helps?
First image is what I believe to be the incorrect texture in the instance. https://gyazo.com/a27edea950ab6ac54435ba5cb34d70b5
Second is what should be there as it doesn't cause issues with female characters.
