I thought I'd check in and see if anyone has found a fix for this.
There was a fix in Fallout 3, but it was on the user side. Try to see if it works for New Vegas, and you'll just have to direct people to do the fix themselves in your mod's Readme. You'll also have to tell every other person who downloads your mod since most people aren't
smart patient enough to read a readme. 8)
Load the Fallout.ini in your Documents folder (c:/Documents and Settings/"You"/My Documents/My Games/FalloutNV ) or whatever
Then add this line below the [General] tab
bLoadFaceGenHeadEGTFiles=1
- Make sure you add this AFTER the lines that start with SetEssential and SetUnessential or this will probably cause a CTD every time you entered a custom cell even after removing the line from the INI file.
- While this will fix the issue for new NPC's, it may cause the problem to occur to some Vanilla NPC's. I'm not sure if a fix ever came up for this.
