I recently discover that many of my recently downloaded mods does not show graphic.... like pony tail, bubble heads, weapon mod extended, mail bags.. they DO function, or it looks like they do... but I couldn't see them... if I try put on the pony tail, my character becomes bold... is this a result of me downloading/updating the Nexus Mod Manager? how can I fix this? Oh I couldn't get the Cadillac radio stations too, nor does the MrTorgue sounds work... but somehow, the game knows I have something there, they just don't show up...

so I guess the issue is actually... my game knows I have some new features... but sound/visual don't register... or something like that... help plz

You need to edit two ini files if you haven't already. See http://wiki.tesnexus.com/index.php/Fallout_4_Mod_Installation for details.
